Calcium Chloride + Sodium Carbonate + Sodium Hydroxide
« on: December 09, 2020, 07:40:01 PM »
Hello! My teacher asked us to observe various chemical reactions and predict their products but there is one reaction that I cannot comprehend which is CaCl2 + Na2CO3 + NaOH. I cannot find any previous experiments about that reaction so I cannot observe it. But on youtube, I saw an experiment on CaCl2 + Na2CO3 + HCl. What happened in that experiment was that when HCl was poured into the solution, the formed solid precipitate was dissolved. What would happen if instead of HCl, it was NaOH?

What was the solid? What was the reaction behind its dissolution in acid?

The solid precipitate was calcium carbonate

I don't think anything should happen at all.

Besides, commercial CaCl2 tend to be somwehat basic due to impurities (CaO?).

Hint: metathesis.
