True or False : Greater the flocculation value of an electrolyte, greater is its coagulating power.

coagultion is the process by which the dispersed phase of a colloid is made to aggregate and thereby separtate from the continuous phase. The minimum concetration of an eletrolyte in milli-moles per litre of the electrolyte solution which required to cause the caogultion of colloidal sol is called coagution value . therefroe higher is the coagulatings power of effective ion, smaller will be the coagultion value of the electrolyte. coagultion value propto = 1/("coagulating power") the coagulation values of differnt electrolytes are different . this behavious can be easily uderstood by Harby - schulze rule which states. the greater is the valency of the effective ion grreater is its coagulating power," which one had the highest coagulating powe?

coagulation is the process by which the dispersed phase of a colloid is made to aggregate and thereby separate from the continuous phase. The minimum concentration of an electrolyte in mili-moles per litre of the electrolyte solution which required to cause the coagulation of colloidal sol is called coagulation value . therefore higher is the coagulating power of effective ion, smaller will be the coagulation value of the electrolyte. the coagulation of colloidal particles to the sol can be caused by : heating, adding electrolyte, adding oppositely charged sol, all of these.

The value of tan A can not be greater than 1.

Assertion : Coagulation power of Al^(3+) is more than Na^(+) . Reason : Greater the valency of the flocculating ion added greater is its power to cause precipitation (Hardy Schulze rule) .

Greater the height of a T.V. transmitter antenna, greater is its coverage. Prove it.

coagultion is the process by which the dispersed phase of a colloid is made to aggregate and thereby separtate from the continuous phase. The minimum concetration of an eletrolyte in milli-moles per litre of the electrolyte solution which required to cause the caogultion of colloidal sol is called coagution value . therefroe higher is the coagulatings power of effective ion, smaller will be the coagultion value of the electrolyte. the ability of an ion to bring about coagulation of a given colloid depends upon :

The coagulating power of an electrolyte for arsenious sulphide sol decreases in the order :

the protective power of the lyophilic colloids es expressed in terms of gold number, a term introduced by Zsigmondy. Gold number is the number of milli - gram of the protective colloid which prevent the coagulation of 10 mLof red gold sol , when 1 mL of a 10 per cent solution of sodium chloride is added to it . thus smaller the gold number of lyophillic colloid, the greater is the protective power. which of the following statement (S) is / are correct? higher the gold number, more protective power of colloid, Lower the gold number, more protective power, Higher the coagulation value, more the coagulation power, lower the coagulation value, higher the coagulation power.

True or False statements: For any function f a local maximum value is always greater than a local minimum value.

True/False: The experimental probability of an event cannot be greater than 1.
