Question

A balanced chemical equation to illustrate how NaNo can be prepared in the laboratory

Answer 1

Explanation:

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.

Answer 2

Explanation:

Nitrogen is prepared in the laboratory by heating on equimolar aqueous solution of ammonium chloride and sodium nitrite. The ammonium nitrite formed as a result of double decomposition reaction, decomposes to form dinitrogen.

NH4Cl(aq)+NaNO2(aq)→NH4NO2(aq)+NaCl(aq)Ammonium nitrateNH4NO2(aq)△NitrogenN2(g)+2H2O(l).
