# How does calcium hydroxide react with nitric acid?

$\text{Option D}$

#### Explanation:

This question illustrates stoichiometry, which requires that all chemical equations be balanced with respect to (i) mass, and (ii) charge.

We have the neutralization of $C a {\left(O H\right)}_{2} \left(a q\right)$, i.e. $\text{lime-water}$:

$C a {\left(O H\right)}_{2} \left(a q\right) + 2 H N {O}_{3} \left(a q\right) \rightarrow C a {\left(N {O}_{3}\right)}_{2} \left(a q\right) + 2 {H}_{2} O \left(l\right)$

And the products are $\text{D}$ as above. Can you write a stoichiometric equation that represents the reaction between $C a {\left(O H\right)}_{2}$, and the diacid, ${H}_{2} S {O}_{4}$?
