The pH of 0.02MNH_(4)Cl solution will be : [Given K_(b) (NH_(4)OH) = 10^(-5) and log 2 = 0.301 ]
The degree of hydrolysis of 0.1 M NH_4Cl solution is 1%. If the concentration of NH_4Cl is made 0.4 M, what is the new degree of hydrolysis :-
A: Molar conductivity of 0.1 M NH_(4)OH solution is less than that of 0.001 M NH_(4)OH solution. R: Dilution increases the degree of ionisation of NH_(4)OH
Amount of (NH_(4))_(2)SO_(4) which must be added to 50mL of 0.2 M NH_(4)OH solution to yield a solution of pH 9.26 is ( pK_(b) of NH_(4)OH=4.74 )
What will be the amount of (NH_(4))_(2)SO_(4) (in g) which must be added to 500 mL of 0.2 M NH_(4)OH to yield a solution of pH 9.35? ["Given," pK_(a)"of "NH_(4)^(+)=9.26,pK_(b)NH_(4)OH=14-pK_(a)(NH_(4)^(+))]
Calculate pH values of (i) 0.2 M H_(2)SO_(4) solution (ii) 0.2M Ca(OH)_(2) solution.
