उत्तर
Sodium hydroxide reacts with zinc nitrate and zinc hydroxide is formed which is soluble in excess of sodium hydroxide
\[\ce{Zn(NO3)2(aq) + 2NaOH(aq) -> Zn(OH)2(s) + 2NaNO3(aq)}\]
Sodium hydroxide reacts with calcium nitrate and forms white ppt. of calcium hydroxide which is insoluble in excess of sodium hydroxide.
\[\ce{Ca(NO3)2 + 2NaOH -> Ca(OH)2 + 2NaNO3}\]
