This method separates the reaction into two half-reactions – one for oxidation and one for reduction. Each half-reaction is balanced separately and then combined. Best for: complex redox reactions, especially in acidic or basic solutions.
Hydrochloric acid is a strong acid and highly soluble in water. It dissociates completely in water. Products of the reaction: CaCl 2 and H 2 O. Calcium chloride (CaCl 2) Calcium chloride is soluble in water and give a colourless aqueous solution. Change of oxidation numbers. Oxidation numbers of atoms are not changed during the reaction.
12 Ιαν 2018 · Long Answer. The balanced equation is CaCl2(s) H2Omm −−−− → Ca2+(aq) + 2Cl-(aq) Explanation: There are three steps in the process of dissolving CaCl2, Step 1. The ions must separate from each other. CaCl2(s) → Ca2+ +2Cl-;ΔH 2. It takes energy to separate the ions from each other, so this step is endothermic. ΔH 2> 0. Step 2.
