The salt that gives the aqueous solution with pH less than 7, is called as____________?
Correct answer: B. Acidic salt
- A. Basic salt
- B. Acidic salt
- C. Neutral salt
- D. Amphoteric salt
Explanation
A salt is called acidic when its aqueous solution has pH less than 7, usually because it contains a conjugate acid or a cation that hydrolyses to produce excess H3O+. Students may choose neutral salt by assuming all salts formed from acid and base are neutral, but salts of strong acids and weak bases can produce acidic solutions.

About Ionic and Molecular Crystals
Ionic crystals contain oppositely charged ions held by electrostatic forces, whereas molecular crystals contain discrete molecules joined by weaker intermolecular forces. Their structures explain differences in melting point, hardness, volatility, solubility and electrical conductivity, especially between solid and molten states.
