$Sr ( OH )_{2} \rightarrow Sr ^{+}+2 OH ^{-}$
It gives high amount of hydroxide ions which are neutralized by the high amount of $H ^{+}$ ions.
$AgCl\downarrow +2N{{H}_{3}}\rightleftharpoons {{\left[ Ag{{\left( N{{H}_{3}} \right)}_{2}} \right]}^{+}}+C{{l}^{-}}$
નીચેના પૈકી શુ ઉમેરવાથી $AgCl$ ની સફેદ અવક્ષેપ મળશે ?
