Question

In the reaction between NaNO3 (aq) and Li2SO4 (aq), will a precipitate form?

Answer 1

Answer: The correct answer is No, this reaction produces no insoluble products.

Explanation:

Precipitate is defined as the insoluble salt which emerges when two different solutions are mixed together. It settles down at the bottom of the flask after some time.

The balanced chemical equation for the reaction of sodium nitrate and lithium sulfate follows:

$2NaNO_3(aq.)+Li_2SO_4(aq.)\rightarrow Na_2SO_4(aq.)+2LiNO_3(aq.)$

By Stoichiometry of the reaction:

2 moles of aqueous solution of sodium nitrate reacts with 1 mole of aqueous solution of lithium sulfate to produce 1 mole of aqueous solution of sodium sulfate and 2 moles of aqueous solution of lithium nitrate.

All the products are aqueous solution and thus, no precipitate is formed.
