MCQ
$NaOH$ is a strong base because
  • ✓
    It gives $O{H^ - }$ion
  • B
    It can be oxidised
  • C
    It can be easily ionised
  • D
    Both $(a)$ 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.
