5 properties of colloids

Brownian movement - When a colloidal solution is viewed through a powerful microscope, the colloidal particles can be seen moving in a random zig-zag path. This zig-zag motion of colloidal particles is called Brownian movement. This random motion is due to collisions b..

Colloidal sols are biphasic in nature. It consists of the dispersed phase and the dispersion medium. In the colloidal solution, each particle is contained within its own surface boundary and therefore has a separate existence from the dispersion mediu..

Applications of Colloids - Colloids have uses in our daily life as well as in various industrial processes. Some of the applications where colloids are present are listed below. 1) Pharmaceutical industry makes use of colloidal solution preparation in many me..

Lithium aluminium hydride is a white, non-volatile crystalline solid, freely soluble in ethers. It is stable up to 120C. It decomposes on heating, liberating hydrogen. It reduces compounds of boron, aluminium, silicon, tin, etc., to form hydrides. ..

Calcium oxide (quicklime) is a white amorphous solid. On heating, quicklime (CaO) glows at high temperatures. This glow of white dazzling light is called lime light. Quicklime melts at 2870 K (2597C). On exposure to the atmosphere, it absorbs moisture and carbon dioxide to finally give calcium c..

1) It is a white powder which is insoluble in water. 2) Hg 2 Cl 2 on heating dissociates into HgCl 2 and Hg...

1) AgCl is obtained as a white precipitate 2) AgCl is insoluble in water. 3) It is soluble in aqueous ammonia..

CuSO 4 is easily soluble in water as it is in the form of crystals. When CuSO 4 is heated it decomposes into copper oxide and SO 3 . ..
