The reaction of potassium chloride (KCl) and sodium carbonate (Na2CO3) in aqueous solution results in a double displacement reaction that produces potassium carbonate (K2CO3) and sodium chloride (NaCl).

Here's the balanced chemical equation:

2KCl(aq) + Na2CO3(aq) → K2CO3(aq) + 2NaCl(aq)

Explanation:

* Double displacement: The positive and negative ions of the reactants switch places. Potassium (K+) from KCl combines with carbonate (CO3^2-) from Na2CO3, and sodium (Na+) from Na2CO3 combines with chloride (Cl-) from KCl.

* Aqueous solution: The reaction occurs in water, where the reactants and products are dissolved.

* No precipitate formation: This reaction does not produce any insoluble solid (precipitate). All the products are soluble in water, resulting in a clear solution.

In summary: The reaction between potassium chloride and sodium carbonate in water is a double displacement reaction that produces potassium carbonate and sodium chloride, both of which remain dissolved in the solution.
