Question

Polystyrene quaternary ammonium is
Options
O Strong acid resin
Weak acid resin
Strong base resin
Weak base resin​

Answer 1

Answer:

Polystyrene (PS) /ˌpɒliˈstaɪriːn/ is a synthetic aromatic hydrocarbon polymer made from the monomer known as styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and rather brittle. It is an inexpensive resin per unit weight.

Answer 2

Polystyrene quaternary ammonium is Strong base resin.

Strong base resin:

• Strong base resins employ a quaternary ammonium groups.
• They are capable of removing or eliminating weak acids such as silicic and carbonic acids to very low levels.
• Polystyrenic Strong base type 1 resins use TMA while Polystyrenic Strong base type 2 resins use DMEA.
• Hence, the correct answer is Strong base resin.

Explanation for the Incorrect options:

• The strongly acidic cation exchange resins have bead-like apperance which have a sulfonic acid group in the cross-linked styrene frame.
• The weakly acidic cation exchange resins consists of carboxylic acid group (-COOH) as an exchange group.
• Resins use the primary-ternary amino groups acts as functional groups which behaves like weak bases and are therefore referred as weakly basic anion exchange resins.
