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 mechanical
Sewage 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.
What else can I help you with?
Are brownies colloids?
After my opinion they are not colloids.
What property of colloids is applied an dyeing?
The property of colloids applied in dyeing is the ability of colloidal particles to remain suspended and evenly dispersed in a solution, allowing for uniform application of dye onto the fabric. This ensures that the dye penetrates the fabric evenly, resulting in a consistent coloration.
How are liquid-liquid colloids like mayonnaise are called?
These colloids are called emulsions.
What are the negative effects of colloids on the environment?
some colloids cause pollution in the environment...some colloids release cfc's that contributes to the ozone layer depletion...
What is the visibility of colloids?
colloids are not visible due to their tiny particle size, (when the colloid is stable).
When colloids are filtered do they leave residue?
Yes, colloids can leave a residue when filtered. Colloids are larger particles that can be trapped by the filter, resulting in a residue left behind after filtration.
Is pizza a colloids?
no
Butter toothpaste paint whipped cream and frogs are all colloids?
Frogs are not colloids, they are amphibians.
What do gelatin milk and stick deodorant have in common?
They are all colloids.they are all colloids
How are solutions and colloids alike?
how are solutions suspensions and colloids alike
What has the author Monzer Fanun written?
Monzer Fanun has written: 'Colloids in drug delivery' -- subject(s): Colloids, Drug Delivery Systems, Drug delivery systems, Pharmacokinetics 'Colloids in biotechnology' -- subject(s): Colloids, Biotechnology, Therapeutic use, Surface-Active Agents
Are all colloids negatively charged?
No, not all colloids have a negative charge. Colloids can have a positive, negative, or neutral charge depending on the type of particles present in the dispersion and the interactions between those particles.
