Question

question 1
a base that does not contain the hydroxide ion is —
a nh₃
b naoh
c hcl
d libr

Explanation:

• \(NaOH\) is a strong base that dissociates to give \(Na^{+}\) and \(OH^{-}\) (hydroxide ion).
• \(NH_{3}\) is a weak base. In water, it reacts as \(NH_{3}+H_{2}O

ightleftharpoons NH_{4}^{+}+OH^{-}\). It does not have hydroxide ion in its formula but produces \(OH^{-}\) through reaction with water.

• \(HCl\) is an acid (\(HCl = H^{+}+Cl^{-}\), no hydroxide ion).
• \(LiBr\) is a salt (\(LiBr=Li^{+}+Br^{-}\), no hydroxide ion).

Answer:

A. \(NH_{3}\)
