Colloidal precipitates are made up of colloidal particles which are really small (1 to 100 micrometres). Since they are small, they have a lot of surface area which promotes surface adsorption. Surface adsorption increases impurities as foreign ions might be present in the counter-ion layer. Crystalline precipitate consists of larger particles, have lesser surface area, thus surface adsorption is less. Hence they are more pure.

What is difference between sol and gel and emulsion?
Sol state is a liquid state .The colloidal particles repel each other. Gel state is more jellylike. The colloidal particles attract each other. emulsion are colloidal system in which both dispersed phase and dispersed medium are in liquid state .
Is an amorphous solid or a crystalline solid more compressible?
Amorphous solids are generally more compressible than crystalline solids because they lack a regular atomic arrangement, allowing their structure to deform more easily under pressure. Crystalline solids have a well-defined lattice structure that makes them more resistant to compression.
Is pet crystalline?
Yes, PET (polyethylene terephthalate) can exhibit crystalline properties. It is a semi-crystalline polymer, meaning it has both amorphous and crystalline regions within its structure. The degree of crystallinity can affect its mechanical properties, thermal stability, and clarity. When processed under certain conditions, PET can form a more crystalline structure, enhancing its strength and durability.
What is the particle size and filterability of precipitates?
The particle size of precipitates can vary depending on the specific chemical reaction and conditions. Generally, they range from nanometers to micrometers in size. Filterability is often influenced by the particle size and shape of the precipitates, as smaller and spherical particles are typically more easily filtered than larger or irregularly shaped particles.
What is a lyophillic solution?
A lyophillic solution is a type of colloidal solution where the dispersed particles are strongly solvated; in this case the solution is more stable.
What are the differences between colloidal precipitate and crystalline precipitate?
Crystalline precipitates have less surface area than the colloidal precipitates, therefore they are more pure. Additionally, crystalline precipitates, because they are larger, are more easily separated from the surrounding solution.
Which has more crystalline polyethylene or Nylon 66?
Nylon 66 is more crystalline than the polyethylene.
What is digestion of precipitates in gravimetric analysis?
In gravimetric analysis, digestion of precipitates refers to the process of allowing a precipitate to remain in contact with its supernatant solution for a period, typically under controlled conditions of temperature and time. This process promotes the growth of larger, purer crystals by allowing smaller particles to agglomerate and dissolve slightly, which can improve the precision and accuracy of mass measurements. Digestion helps to reduce the presence of impurities and enhances the overall yield of the desired compound. Ultimately, it contributes to more reliable results in quantitative analysis.
An emulsion is a colloidal dispersion of a?
An emulsion is a colloidal dispersion of two or more immiscible liquids, where one liquid is dispersed in the other in the form of small droplets.
What element is shiny but will tarnish after the air hits it awile?
Silver. The purer the silver the more rapidly it will tarnish.
What happens when a persistent dialysis of a colloidal solution is carried out?
When a colloidal solution undergoes persistent dialysis, the smaller solute particles and ions are removed from the solution, while the larger colloidal particles remain trapped within the dialysis membrane. This process gradually purifies the colloidal solution by eliminating impurities and small molecules, leading to a more concentrated and refined colloid. Over time, the osmotic pressure difference may also affect the distribution of particles, potentially altering the colloidal properties. Ultimately, prolonged dialysis can enhance the stability and quality of the colloidal dispersion.
Why is a solution saturated?
A solution is saturated when it can hold no more solute, and any additional solute precipitates.

Colloidal silver is 650 times more potent than penecillin is this true?
No, this statement is not true. Colloidal silver is not considered more potent than penicillin. Penicillin is an antibiotic medication that is commonly used to treat a variety of bacterial infections, whereas colloidal silver is not typically used for bacterial infections and its efficacy and safety are debated in the medical community.
Why is gold more expensive than iron?
gold is more expensive than iron simply because iron is more common and gold is also a purer metal
What chemical compound is a yellow liquid that precipitates when mixed with certain chemicals?
Impossible to answer, more details needed.
