Answer;
The balanced reaction would be;
BaCl2(aq) + 2 KOH(aq) = Ba(OH)2(s) + 2 KCl(aq)
Explanation;
-A precipitation reaction also referred to as double decomposition reactions occurs when two soluble salts such as barium chloride (BaCl2) and potassium hydroxide (KOH) reacts to form an insoluble salt (Ba(OH)2).
-The insoluble salt produced falls out of the solution in the form of a precipitate, which is the reason as to why the reaction is known as precipitation.
-This type of reaction occurs when cations and anions in aqueous solution combine to form the precipitate.
That is; Ba²⁺(aq) + OH⁻(aq) → Ba(OH)₂(s)
