The process of separating two immiscible liquids uses: MCQ with Answer and Explanation

Explanation:
Hydrochloric acid (HCl) dissociates completely in water, making it a strong acid. Acetic acid (CH₃COOH), carbonic acid (H₂CO₃), and citric acid are weak acids—they partially ionize. Other strong acids: H₂SO₄ (first dissociation), HNO₃, HBr, HI, HClO₄. Strong acids have very large Ka values. pH of 0.1 M HCl is about 1.

Explanation:
Enzymes are complex organic molecules that act as biological catalysts in living organisms. Chemically, most enzymes are globular proteins. They are highly specific to their substrates and work optimally at body temperature and near-neutral pH, unlike many industrial catalysts that require extreme conditions.

Explanation:
Sulphuric acid (H₂SO₄) is known as the 'King of Chemicals' because of its extensive use in various industries, including fertilizers, dyes, detergents, and petroleum refining. Its production is often considered an indicator of a country's industrial strength and economic development.
