$${H}_{{{2}}}{S}$$ is passed through $${\left({C}{H}_{{{3}}}{C}{O}{O}\right)}_{{{2}}}$$ Zn and $${Z}{n}{C}{I}_{{{2}}}$$ solutions separately. White ppt. will be noticed in :
(A) $${\left({C}{H}_{{{3}}}{C}{O}{O}\right)}_{{{2}}}{Z}{n}$$ solution
(B) $${Z}{n}{C}{I}_{{{2}}}$$ solution
(C) both (a) and (b)
(D) none of these

$${Z}{n}{\left({C}{H}_{{{3}}}{C}{O}{O}\right)}_{{{2}}}$$ will furnich $${C}{H}_{{{3}}}{C}{O}{O}{H}$$, a weak acid which will not influence dissociation of $${H}_{{{2}}}{S}$$ to apprecible amount and thus ZnS will be prercipitated.
