Final answer:
KCl, H₂SO₄, AgNO₃, and NaCl are soluble in water; BaSO₄ and AgCl are insoluble; Ca(OH)₂ and Al(OH)₃ are sparingly soluble according to solubility rules.
Step-by-step explanation:
The question pertains to the solubility of various compounds in water. According to solubility rules and the provided references, we can determine the solubility of the compounds listed:
- KCl - Soluble (Rule 1)
- H₂SO₄ - Soluble (Strong acid)
- BaSO₄ - Insoluble (Rule 5)
- Ca(OH)₂ - Sparingly soluble (Rule 6)
- AgNO₃ - Soluble (Nitrates are soluble)
- NaCl - Soluble (Rule 1)
- Al(OH)₃ - Sparingly soluble (Rule 6)
- AgCl - Insoluble (Exception to Rule 1)
The mentioned correct option in the final answer would consider KCl, H₂SO₄, AgNO₃, and NaCl as soluble in water; BaSO₄ and AgCl as insoluble; and Ca(OH)₂ and Al(OH)₃ as sparingly soluble.
