Question

When compound X is dissolved in water, it dissociates as shown:
$X\to A^{-}+O{H}^{-}.$
Then X is:

• A. Arrhenius acid
• B. Arrhenius base
• C. Neutral
• D. Cannot be determined.

Answer 1

The correct option is B

Arrhenius base

Since X dissociates into $O{H}^{-}$ on dissolving in water. An Arrhenius base gives out $O{H}^{-}$ ions on dissolving in water. Hence, X is an Arrhenius base.
