Question

Which of the following is NOT an Arrhenius base?
Options
A Ca(OH)₂
B NH₃
Correct Answer
C NaOH
D KOH
Correct Answer

Option B is the correct answer.

Detailed Explanation

Arrhenius bases produce OH⁻ in water. NH₃ (ammonia) does not directly produce OH⁻; it accepts a proton from water to form NH₄⁺ and OH⁻, so it is a Brønsted base but not an Arrhenius base by strict definition.

Hint

Arrhenius base releases OH⁻ ions directly.
