What happens when you mix calcium chloride with baking soda and add water?

Answer 1

CaCl2 hydrolysis in water is noted to be exothermic and forms Hydrochloric acid., a strong acid.

CaCl2 + 2 H20 <----> Ca(OH)2 + 2 HCl

As such, this acid salt has been proposed as a safer acid substitute.

Now, it is well know that the reaction of an acid with NaHCO3, baking soda, produces CO2. In the case of HCl:

2 HCl + 2 NaHCO3 --> 2 NaCl + 2 H2O + 2 CO2

So the final reaction products will include Ca(OH)2, NaCl and CO2.

Answer 2

it bubbles and if you touch the calcium chloride it feels warm the baking soda just gives color

Answer 3

Carbon dioxide
