MCQ
$NaOH$ is a strong base because
- ✓It gives $O{H^ - }$ion
- BIt can be oxidised
- CIt can be easily ionised
- DBoth $(a)$ and $(c)$
✓
Answer
Correct option: A.
It gives $O{H^ - }$ion
a
Strong bases are commonly formed from the hydroxides of alkali metals and alkaline earth metals. $NaOH$ (sodium hydroxide) is a strong base because it gives $OH ^{-}$ ions easily in water.
