Question

Write a balanced chemical equation with state symbols to illustrate how NaNO3,can be prepared in the laboratory.Explain why NaNO3,cannot be prepared utilizing the same method used for the preparation of CaCO3.

Answer 1

Neutralization of nitric acid with sodium hydroxide makes it possible to obtain sodium nitrate in the laboratory in its pure form.

HNO3 + NaOH → NaNO3 + H2O

NaNO3 cannot be prepared utilizing the same method used for the preparation of CaCO3, because calcium carbonate is not soluble in water, and sodium nitrate is soluble in water.
