A buffer solution contains `1` mole of `(NH_(4))_(2)SO_(4)` and `1` mole of `NH_(4)OH(K_(b)=10^(-5))`. The `pH` of solution will be:

A buffer solution contains 0.02 moles of NH_4OH and 0.03 moles of NH_4CI dissolved in 1 litre of the solution. Calculate the pH of the solution. Dissociation constant of NH_4OH "is" 1.8 xx 10^-5

A buffer solution contains 0.2 mole of NH_4 OH and 0.2 mole of NH_4 Cl per litre. The PK_b of NH_4 OH is 4.75 The pH of the buffer will be

Calculate pH of the buffer solution containing 0.15 mole of NH_(4)OH " and " 0.25 mole of NH_(4)Cl. K_(b) " for " NH_(4)OH " is " 1.98 xx 10^(-5) .

Calculate pH of the buffer solution containing 0.15 mole of NH_(4)OH " and " 0.25 mole of NH_(4)Cl. K_(b) " for " NH_(4)OH " is " 1.98 xx 10^(-5) .
