Question

When compound X is dissolved in water, it dissociates as shown below:
$X\to A+O{H}^{-}.$
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 to give $O{H}^{-}$ on dissolving in water. An Arrhenius base gives out $O{H}^{-}$ ions on dissolving in water. Hence, X is an Arrhenius base.
