Identify $A, B$ and $C$ in the following reactions and write the chemical name of $A, B$ and $C$.
$(i)$ $HNO_{3} + NaOH \rightarrow \underline{A} + H_{2}O$
$(ii)$ $\underline{B} + Ca(OH)_{2} \rightarrow CaSO_{4} + 2H_{2}O$
$(iii)$ $HCl + \underline{C} \rightarrow KCl + H_{2}O$

(N/A) The given reactions are neutralization reactions where an acid reacts with a base to form salt and water.
$(i)$ $HNO_{3} + NaOH \rightarrow NaNO_{3} + H_{2}O$. Here,$A$ is $NaNO_{3}$ (Sodium nitrate).
$(ii)$ $H_{2}SO_{4} + Ca(OH)_{2} \rightarrow CaSO_{4} + 2H_{2}O$. Here,$B$ is $H_{2}SO_{4}$ (Sulphuric acid).
$(iii)$ $HCl + KOH \rightarrow KCl + H_{2}O$. Here,$C$ is $KOH$ (Potassium hydroxide).
