State Hardy-Schulze rule which deals with the coagulation of colloids by the addition of an electrolyte.

Which does not cause coagulation of colloidal solution?

Explain how colloids get coagulated on addition of salts.

The protective power of a lyophilic sol is : Hardy - schulze rule, propotional to the quantity of electrical charge on it, measured in terms of gold number, determined by the size of its colloidal particles

How will these colloidal solutions respond to addition of small amount electrolyte solution into each?

The existence of charge on colloidal particles is confirmed by electrophoresis experiment. In the coagulation of,a negative sol, the coagulating power is in the order AI^(3+) > Ba(2+) > Na^+ . Name and state the rule behind this?

Statement 1: The conversion of fresh precipitate to colloidal state is called peptization. Statement 2 : It is caused by addition of common ions.

State the Motor Rule. If the directions of current in the conductor and the magnetic field are the same, in which way will the conductor move?

Which of the following statements regarding carbonyl group is not correct? The carbon atom of the carbonyl group in aldehydes and ketones is sp^(2) hybridised, The carbon atom of the carbonyl group in the transition state formed during the addition reaction across it sp^(3) hybridised, An aryl group stabilizes an aldehyde more than the transition state, The aryl group in aromatic aldehydes speeds up the addition reaction across the carbonyl group

Colloids can be converted into precipitate on the addition of electrolytes. a. Name the above phenomenon B. What do you mean by gold number and coagulation value?

Which of the following electrolytes will be most effective in the coagulation of gold sol?
