Question

According to Lowry and Bronsted system, the chloride ion $\left({Cl}^{-}\right)$ in aqueous solution is a:

• A. Weak base
• B. Strong base
• C. Weak acid
• D. Strong acid

Answer 1

Answer: (A)

Weak base

According to Lowry and Bronsted system, the chloride ion (Cl${}^{-}$) in an aqueous solution is a weak base.

A strong acid like HCl donates its proton so readily that there is essentially no tendency for the conjugate base Cl${}^{-}$ to reaccept a proton. Consequently, Cl${}^{-}$ is a very weak base.

A strong base like the H${}^{-}$ ion accepts a proton and holds it so firmly that there is no tendency for the conjugate acid H${}_2$ to donate a proton.

Hence the correct option: A
