Answer : When we add sodium carbonate with calcium chloride we get the below reaction :
[tex]Na_{2}CO_{3} + CaCl_{2} ----\ \textgreater \ CaCO_{3} + 2NaCl [/tex]
We observe that the calcium carbonate is precipitate out after the double displacement reaction takes place amongst the sodium carbonate and calcium chloride reactant.
A solid white precipitate of calcium carbonate is formed as insoluble solid in the solution. Rest all other remains in the ionic form in the aqueous state.
