Question

Match the following

$$\begin{array}{cc}coloumnI& coloumnII\\ \left(I\right)(N{H}_4{)}_{2}S{O}_4& \left(P\right)h=\sqrt{\frac{K_H}{C}}\\ \left(II\right)KCl& \left(Q\right)P^H=\frac{1}{2}[p^{K_w}+p^{K_a}+logc]\\ \left(III\right)\left(C{H}_3\right)COOK& \left(R\right)K^H=\frac{K_w}{K_a\ast K_b}\\ \left(IV\right)(N{H}_4{)}_{2}S& \left(S\right)\left[H^{+}\right]=\left[O{H}^{-}\right]\end{array}$$

• A. I P,S ; IIP,S ; IIIP,Q ; IV S
• B. IP ; IIS ; IIIP,Q ; IVR
• C. IP,Q,R ; IIS ; IIIP,S ; IVP,R
• D. IP,R ; IIS ; IIIP,Q ; IVS

Answer 1

The correct option is B

IP ; IIS ; IIIP,Q ; IVR

Its based on salt hydrolysis.

I$\to$P ; II$\to$S ; III$\to$P,Q ; IV$\to$R
