हिन्दीConsider the following statements regarding solubility product (\( K_{\text{sp}} \)) and precipitation: (A) For a salt of general formula \( \text{M}_x\text{X}_y \), the solubility product is given by \( K_{\text{sp}} = x^x y^y S^{x+y} \). (B) Passing \( \text{HCl} \) gas through saturated \( \text{NaCl} \) solution causes precipitation of pure \( \text{NaCl} \) due to the common ion effect. (C) Precipitation occurs when the ionic product is less than the solubility product (\( Q_{\text{sp}} < K_{\text{sp}} \)). (D) For a saturated solution of \( \text{BaSO}_4 \), the condition \( K_{\text{sp}} = [\text{Ba}^{2+}][\text{SO}_4^{2-}] \) holds true. Choose the correct answer from the options given below:
Correct answer · Option 1
(A), (B) and (D) only
Explanation
Precipitation occurs when \( Q_{\text{sp}} > K_{\text{sp}} \), so (C) is incorrect. Statements (A), (B), and (D) are correct.
