An aqueous solution of (NH_(4))_(2)SO_(4) is acidic. Explain.

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)^(+))]

A 2L solution was prepared by mixing of NH_(3) and (NH_(4))_(2)SO_(4) . If pH of solution was found 8 and solution contains one mole of NH_(3) then moles of (NH_(4))_(2)SO_(4) was taken will be [pKb of NH_(3)=5] 2 4 5 1
