Vedclass · Answer

(d) ${K_a} = \frac{{[{H^ + }]\,\,[C{N^ - }]}}{{[HC{N^ - }]}}$

$6.2 	imes {10^{ - 10}} = \frac{{[{H^ + }]\,\,[0.02]}}{{[0.01]}}$

$[{H^ + }] = \frac{{6.2 	imes {{10}^{ - 10}} 	imes 0.01}}{{0.02}} = 3.1 	imes {10^{ - 10}}$

What is $[{H^ + }]$ of a solution that is $0.01\,M$ in $HCN$ and $0.02\,M$ in $NaCN$ $({K_a}$for $HCN = 6.2 \times {10^{ - 10}})$
