Question

What kind of salt is obtained from the reaction of a weak acid and a strong base?
1. Acidic Salt
2. Alkaline Salt
3. Neutral Salt
4. Double Salt

Answer 1

Correct Answer - Option 2 : Alkaline Salt

The correct answer is Alkaline Salt.

• Alkaline Salt
  • These are formed by incomplete neutralization bases.
  • These salts still contain one or more hydroxyl groups in their molecules.
  • Its aqueous solution turns red litmus blue.
  • Example: CaCO₃, Zn(OH)Cl, etc.

• Acidic Salt
  • These are formed by the incomplete neutralization of acids.
  • These salts still contain one or more replaceable hydrogen groups in their molecules.
  • Its aqueous solution turns blue litmus red.
  • Example: ZnCl₂, HgCl₂, Fe₂ (SO₄)₃, HgSO₄ etc
• Neutral Salt
  • Normal Salt is obtained by the reaction of a strong acid with a strong base.
  • Its aqueous solution has no effect on litmus paper.
  • Example: KCL, NaCl
• Double Salt
  • It is a mixture of two salts and exists only in a solid-state.
  • Example: Potash alum, Mohr Salt.​
