Answer 2

Electrical conductivity:

Explanation:

• Conduction of electric charge depends only on the ions.
• Higher is the number of ions higher is the electrical conductivity.
• Electrical conductivity is a property that allows electricity to flow through a material.
• So, we have to find the acid which gives stable ions in a solution.
• HCN produces 1 H⁺ ion.
• CH₃COOH produces 1 H⁺ ion.
• H₂CO₃ produces 1 H⁺ ion.
• H₂SO₄ produces 2 H⁺ ions.
• Hence H₂SO₄ has maximum ion among given solutions having 0.2 M molarity.
• So 0.2 M H₂SO₄ has maximum electrical conductivity

Correct option is d: 0.2 M H₂SO₄
