state true or false? Barium chromate is insoluble in dilute acetic acid

Explanation

**Step-by-Step Solution:**

1. **Understanding the Solubility of Barium Chromate:**
- Barium chromate (BaCrO4) is known to be a sparingly soluble salt. This means that it does not dissolve well in water or in dilute acids.

2. **Reaction with Acetic Acid:**
- When barium ions (Ba²⁺) are present in a solution and potassium chromate (K2CrO4) is added, a reaction occurs. The barium ions react with the chromate ions (CrO4²⁻) to form barium chromate, which precipitates out of the solution.
- The reaction can be represented as:
\[ \text{Ba}^{2+} (aq) + \text{K}_2\text{CrO}_4 (aq) \rightarrow \text{BaCrO}_4 (s) + 2\text{K}^+ (aq) \]

3. **Effect of Acetic Acid:**
- Acetic acid (CH3COOH) is a weak acid and does not provide sufficient protons to dissolve barium chromate. Therefore, barium chromate remains insoluble in dilute acetic acid.

4. **Conclusion:**
- Since barium chromate does not dissolve in dilute acetic acid, the statement "Barium chromate is insoluble in dilute acetic acid" is **True**.

**Final Answer:**
True.
