Question

If aqueous solutions of potassium chromate and barium chloride are mixed, a bright yellow solid (barium chromate) forms and settles out of the mixture, leaving potassium chloride in solution. Write a balanced chemical equation for this process.

Answer 1

Answer:

K₂CrO₄ (aq) +  BaCl₂ (aq) → BaCrO₄ (s) ↓ + 2KCl (aq)

Explanation:

K₂CrO₄ → Potassium chromate

This salt dissociates as this: K₂CrO₄ →  2K⁺  +  CrO₄⁻²

BaCl₂ → Barium chloride

This salt dissociates as this: BaCl₂ → Ba²⁺ +  2Cl⁻
