Explain what is observed when
(i) Silver Nitrate solutio is added to potassium iodide solution.
(ii) The size of the finest gold sol particles increases in the gold sol.
(iii) Two oppositely charged sols are mixed in almost equal proportions.

Explain what is observed when silver nitrate solution is added to potassium iodide solution?

When silver nitrate solution is added to potassium iodide solution then the sol produced is

Explain what is observed when the size of the finest gold sol particle increases in the gold sol?

Give reason for the following observations: When silver nitrate solution is added to potassium iodide solution, snegatively charged colloidal solution is formed.

What happens when NaCl solution is added to a gold sol?

Explain what is observed when (i) an electrolyte is added to ferric hydroxide sol. (ii) an emulsion is subjected to centrifugation. (iii) direct currect is passes through a colloidal sol.

Give reason for the following observations : (i) When Silver nitrate solution is added to Potassium iodide soltuion , a negatively charge colloidal solution is formed. (ii) Finely divided substance is more effective as an adsorbent. (iii) Lyophilic colloid are also called reversible sols.
