The compound potassium carbonate is a strong electrolyte. Write the reaction when solid potassium carbonate is put into water
Andrew [12]

Answer:

K2CO3 (aq) ---> 2K+ (aq) + CO32- (aq)

Explanation:

Dissociation refers to the ability of an ionic compound to breakdown into its respective ions. An ionic compound is formed by the combination of a positive ion (cation) and a negative ion (anion). When these ionic compound dissolves in water, it dissociates i.e. separates into its constituent ions.

In this question involving potassium carbonate being described as a strong electrolyte, which means that it dissociates completely in water as follows:

K2CO3 (aq) ---> 2K+ (aq) + CO32- (aq)
