A heterogeneous mixture in which the particles equally spread in the solution is called a colloid or colloidal solution. The term colloid is often used in particular for the scattered material alone in the colloidal solution, but the term colloidal suspension usually refers to the entire mixture. ...
Solvent-hating materials such as iron, mercury, arsenic, and precious metals such as gold andplatinumrequire special handling. These materials usually combine in solutions called colloidal solutions; lyophobic colloids are one of the two main types of colloidal solutions. As solvent-hating materials do...
There are two types of quenching. What are they? What are their advantages, respectively? When the two types of quenching are applied, which one is first? Why? What do you mean by colloidal dispersion? What are its various types?
Milk is a mixture. It is a liquid(butterfat) in liquid(water) type of colloidal solution in which butterfat is the dispersed phase and water is the dispersing medium, with casein protein as an emulsifying agent.Answer and Explanation: ...
athis indicates that during immersion HDG steel in the phosphating solution containing silicate additives,colloidal silica maybe also participate in the formation of the coatings and the coverage of the coatings is thus increased. 这表明在浸没HDG钢期间在包含硅酸盐添加剂的磷酸盐化的解答,胶质硅土也可能...
Blood isa colloidbecause in blood the blood cell size is between 1nm to 100nm. A mixture in which one substance is divided into minute particles (called colloidal particles) and dispersed throughout a second substance. ... Blood is a colloidal solution of an albuminoid substance....
What is hydrocolloid impression material? Hydrocolloid impression materials arebased on the colloidal suspension of polysaccharide in water. ... Agar hydrocolloid was the first successful elastic impression material to be used in dentistry. It is an organic hydrophilic colloid extracted from certain types...
A mixture qualifies as a colloid when its particles are larger than those in a solution but small enough to remain suspended indefinitely without settling. 10 Can colloids be separated by conventional filtration? Conventional filtration typically cannot separate colloidal particles due to their small siz...
What is the problem to be analyzed in this investigation? What property of colloidal solutions is explained by the Brownian movement experiment? What is observed when chlorine reacts with potassium bromide? What bond is responsible for the absorption observed at 3500 cm^{-1}? (a) OH (b) NH...
What do you mean by colloidal dispersion? What are its various types? What is meant by a mixed-crystal formation? What does the term mixture mean in chemistry? What is a form of matter that has its own unique properties that make it different from every other substance called?
