The reaction between potassium chromate (K₂CrO₄) and copper sulfate (CuSO₄) is a double displacement reaction, resulting in the formation of copper chromate (CuCrO₄) and potassium sulfate (K₂SO₄). Here's the balanced chemical equation:

K₂CrO₄ (aq) + CuSO₄ (aq) → CuCrO₄ (s) + K₂SO₄ (aq)

Here's a breakdown:

* K₂CrO₄ (aq): Potassium chromate, dissolved in water (aqueous).

* CuSO₄ (aq): Copper sulfate, dissolved in water (aqueous).

* CuCrO₄ (s): Copper chromate, a solid precipitate that forms.

* K₂SO₄ (aq): Potassium sulfate, dissolved in water (aqueous).

Important Notes:

* Solubility: Copper chromate is sparingly soluble in water, meaning it will precipitate out of the solution as a solid.

* Color Changes: The solution will change color as the reaction progresses. Potassium chromate is yellow, copper sulfate is blue, and copper chromate is a reddish-brown color.

* Net Ionic Equation: The net ionic equation focuses on the species that actually participate in the reaction:

CrO₄²⁻ (aq) + Cu²⁺ (aq) → CuCrO₄ (s)

This equation shows that the chromate ions (CrO₄²⁻) and copper ions (Cu²⁺) combine to form the precipitate.
