Potassium carbonate reaction with water equation?
What is the equation of the reaction KCO3 + H2O? also, what are the 5 ions and 1 molecule formed during the disassociatin reactions. Ex: OH- and H3O+ ions. Please explain the process, I got stuck after 2K+ +OH- + HCO3. Thanks!

Potassium carbonate doesn't really react with water, it dissolves giving 2K+ and one CO3 2- ion. There are also H+ and OH- ions from the water.
Since carbonic acid is a very weak acid, there will also be equilibria to that and HCO3- from the ions.
weak acid H2CO3 Conjugate base HCO3-
H+(aq) + HCO3-(aq) <--> H2CO3(aq)

KCO3 dissolves in water. The complete ionic formula would have K^+ and CO3^2-. It will form a solution. CaCl2 will dissolve into Ca^+ and 2Cl^-. Complete ionic K^+ + CO3^2- + Ca^+ + Cl^- -> CaCo3(s) + KCl(aq). Molecular: KCO3 + CaCl2 -> CaCO3 + KCl. It doesn't have to balance
