On the basis of Hardy-Schulze rule explain why the coagulating power of phosphate is higher than chloride.

Write notes on Hardy Schulze Rule ?

Explain with reason : the reducing power of phosphine is higher than that of ammonia.

Give reasons : Boiling point of alkyl bromide is higher than alkyl chloride.

Explain why Most metal fluoride are ionic in nature than metal chloride.

select the false statement (S) : Brownian motion and Tyndall effect are shown by true solutions, sorption process is combinations of adsorption and absorption process, Law Hardy schulze is related with coagulation of a sol, Higher is the gold number greater will be the protective power of a colloid.

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.

Steel is more elastic than rubber. Explain why?
