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?
