Identify the strong electrolyte.

Options

  1. ACaCl ₂
  2. BCa(OH) ₂
  3. CNH ₃
  4. DHCN

Correct answer

A. CaCl ₂

Step-by-step solution

Strong electrolytes are substances that completely dissociate into ions in aqueous solutions. They generally include strong acids, strong bases, and soluble salts. CaCl ₂ is a soluble salt that dissociates completely into Ca ²⁺ and Cl ⁻ ions in aqueous solution, making it a strong electrolyte. Ca(OH) ₂ is a strong base but is only sparingly soluble in water. NH ₃ is a weak base and HCN is a weak acid, meaning they only partially dissociate in water and are therefore weak electrolytes. Answer: CaCl ₂
