Web16 feb. 2024 · There are three main steps for writing the net ionic equation for K2CO3 + FeCl3 = KCl + Fe2 (CO3)3 (Potassium carbonate + Iron (III) chloride ). WebH2CO3 is considered an acid because it ionizes in H+ and HCO3-. Some of the HCO3- will bond with water and form OH- and H2CO3 again. This is an equilibrium. But If we have only one HCO3- that didn't yet bonded to water and formed H2CO3 again, we will have more H+ in the medium, and it will be acid.
