What compound is formed from sodium bicarbonate and calcium chloride?

Answer 1

When calcium chloride dissolves, it is rather exothermic (which makes it a good deicer for sidewalks).

After mixing: the sodium and chloride ions will remain in solution and do nothing. The bicarbonate and calcium will react in a strange way.

Ca2+ + 2 HCO3- → CaCO3 + H2CO3

As the calcium carbonate drops out of solution, the equilibrium of this reaction is further driven off to the right thus creating more carbonic acid. Carbonic acid easily decomposed to form water and carbon dioxide.

H2CO3 → H20 + CO2

So, when you mix calcium carbonate and sodium bicarb, you get: Carbon dioxide gas, calcium carbonate solid, water and sodium and chloride ions.

Answer 2

Sodium chloride is formed from sodium ions and chloride ions.

There are no bicarbonate ions in sodium chloride.
