Differentiate dispersion method from condensation method?
In the preparation of colloids, using the dispersion method, larger particles of the substance are broken down into much smaller parts. Using the condensation method, smaller particles are dispersed and condensed to colloidal size.
What is the difference between sedimentation and centrifugation?
sedimentation is the tendency for particles in suspension to settle down when there is a stirring in it.this is due to there motion through the fluid in response to the force acting on them centrifugation is the process of increasing the level of sedimentation by using a centrifuge.
How would you make a concept map using these words matter element compound mixture solution suspension and colloid?

What is used to detect trajectories of nuclear particles using charged wires?
Wire chambers
If water and oil are combined in a container the resulting liquid is a?
its either a mess, or they are seprate oil on top water on th bottom, or it would be an emusifacation, like mayo its either a mess, or they are seprate oil on top water on th bottom, or it would be an emusifacation, like mayo It is A. emulsionIf water and oil are combined in a container the resulting liquid is an immiscible mixture. It is also considered a suspension, which is where the particles in suspension are larger than those found in solution. The suspension can be distributed evenly by a method like shaking, but will settle out.
Why are colloids important in medicine?
Colloids are important in medicine because they are easier to absorb through tissues. This makes using colloidal medicine invaluable for patients.Colloids are important in medicine as they ensure even distribution with worry of settling. The particles will remain evenly dispersed throughout a colloidal suspension.

What is the term for a mixture with fine insoluble particles in it that eventually settle out to form a sediment?
A Suspension Here the particle size can be viewed by the naked eye. The particles display the tyndal effect where the particles are used as the medium for light rays. The particles also settle down after a short period of time and this mixture can be seperated using a funnel or evaporation(if it is an aqueous solution).
What are the application of colloids?
Applications of colloids are unlimited. Colloids find its applications in everyday life phenomena. Some of important applications of colloids are discussed.Purification of waterWater contains colloidal impurities .These impurities can be weeded out by using electrolyte like Alum. Alum is positively charged Al3+ ion which attracts negatively charged colloidal impurities. These neutralized particles settle down and pure water is decanted off. Thus Alum is used to remove dirt and impurities present in the colloidal solution. Food ItemsLarge numbers of food articles which we use in our daily life are colloidal in nature. For example, milk, butter and ice creams are colloidal in nature. MedicineMost of the medicines are colloidal in nature. Colloidal calcium and gold are administered by injections to raise the vitality of human system. Smoke Precipitation using Cottrell precipitatorColloidal particles of Smoke and dust are major source of pollution in big industrial cities. Smoke precipitation is technique of precipitating smoke particles present in air. Smoke particles are the electrically charged colloidal particle suspended in air. To remove these particles from air, Cottrell precipitator is used. Cottrell precipitator uses principle of electrophoreses (movement of colloidal particles under influence of electric field) to weed out smoke particles. Air containing smoke and dust particles are allowed to pass through metal electrodes present inside Cottrell precipitator. These charged particles moves towards oppositely charged electrodes and get deposited there from which they are scrapped mechanicalSewage disposalDirt and mud particles are electrically charged. By applying electric field in sewage tank, dirt particles reach the oppositely charged electrode, get neutralized and are coagulated. These coagulated particles are suspended in solution and are easily removed. Artificial rainColloids find another application in producing artificial rain. Cloud consists of charged particles of water dispersed in air. These particles are neutralized by spraying oppositely charged particles over a cloud. These neutralized particles of water combine to form large water drops. Thus, artificial rain is caused by the aggregation of minute particles of water to form large particles.
Does colloidal silver kill mollusum?
On the internet, there are many anecdotal reports of colloidal silver alleviating or even curing molluscum infections. But it is not recognized by orthodox medicine as an effective treatment. Most molluscum victims who have reported success with colloidal silver agree that nano-particle colloidal silver works better than conventional colloidal silver. That means colloidal silver solutions containing very tiny silver particles between one and one hundred nanometers in size works best. According to internet reports, this is because the smaller silver particles are best able to penetrate the molluscum cell. "Nano-particle colloidal silver" can be found on the internet by googling that phrase. Two good brands are Sovereign Silver and ASAP Silver. From what I've seen, most people who have reported using colloidal silver successfully against molluscum say that it took many days or even weeks worth of treatment. Most of them used colloidal silver orally as well as topicallly, drinking two or three teaspoons or more daily, and also spraying colloidal silver directly onto the molluscum outbreak several times a day using a pump spray bottle, and allowing the colloidal silver to air dry on the skin. Unfortunately, nano-particle colloidal silver is very expensive, often costing anywhere from $15 to $30 for a tiny, four-ounce bottle. Such a small bottle would last about a week, if that, when treating molluscum. You might be better off purchasing a device called a colloidal silver generator, that allows you to make your own high-quality colloidal silver for just a few cents per each quart batch. That way, you can make all of the colloiidal silver you want, any time you need it, for only a few pennies. If you choose to go this route, make sure you get a colloidal silver generator that can produce the tiny, nano-particles of colloidal silver, rather than one that produces only a conventional colloidal silver solution. I personally use the new Micro-Particle Colloidal Silver Generator from www.TheSilverEdge.com. It produces silver particles as low as .0008 microns in size, which is a fraction of a single micron, or smaller than a single nanometer. No other colloidal silver generator I know of produces silver particles that small. You can read about it on several web sites, including www.TheSilverEdge and www.MicroParticleGenerator.com You can see a Transmission Electron Microsope slide of these tiny silver particles produced by the new Micro-Particle Colloidal Silver Generator here: http://thesilveredge.com/mp5.shtml And you can view short, 3-minute video showing how this simple machine works, here: http://thesilveredge.com/vidclip.shtml Finally, you can read tons of articles about the amazing, infection-fighting power of colloidal silver at the Colloidal Silver Secrets blog, at www.ColloidalSilverSecrets.blogspot.com
Can you separte a colloidal dispersion using a filter paper?
yes!
What type of mixture is characterized by settling of particles?
A Suspension Here the particle size can be viewed by the naked eye. The particles display the tyndal effect where the particles are used as the medium for light rays. The particles also settle down after a short period of time and this mixture can be seperated using a funnel or evaporation(if it is an aqueous solution).
Why some medicine as antibiotics are called suspension?
In this context, the "suspension" is the liquid the antibiotic is mixed with, in order to make taking it easier or more effective. Kids, for example, take liquids better than pills. So they're prescribed antibiotics in suspension.
Is a solution a mixture explain?
Yes, it is a type of mixture as mixtures are made of 4 categories: Mechanical Mixture (which is different than a solution), Colloid, Suspension, and Solution. So yes, a solution is a type of mixture just not a Mechanical Mixture.
Many bridges are constructed using this type of architecture..?
steel cable suspension
What are the uses of properties of colloids?
colloidal properties of substances used in wide areas. In industries, using electrical precipitation method to reduse the amount of co2, so2, dust etc in the smoke comes out from the chimney. Another one is the cleansing action of soap .then paints ,latex are produce by using colloidal properties
