Question

A precipitate of calcium carbonate is formed when an aqueous solution of sodium carbonate reacts with aqueous calcium chloride. What is the balanced equation for this reaction?

Answer 1

Answer:

$Na_{2}CO_{3}(aq) + CaCl_{2} (aq)\rightarrow 2NaCl (aq) + CaCO_{3}(s)$

Explanation:

  A precipitate of calcium carbonate is formed when an aqueous solution of sodium carbonate reacts with aqueous calcium chloride . Balanced equation of this reaction ,

                  $Na_{2}CO_{3}(aq) + CaCl_{2} (aq)\rightarrow 2NaCl (aq) + CaCO_{3}(s)$ (↓)

This reaction takes place when both reactants present in aqueous conditions, while calcium chloride precipitate separated from aqueous solution by filtration of an aqueous solution. This filtration of precipitate formed in the reaction left behind the residues aqueous solution .
