Question

NaOH is a strong base because

• A. it gives ${OH}^{-}$ ions.
• B. it can be oxidised.
• C. it can be easily ionised.
• D. it can be reduced.

Answer 1

The correct option is A

it gives ${OH}^{-}$ ions.

NaOH dissociates completely in water to give ${Na}^{+}$ and ${OH}^{-}$ . It is considered as a strong base because all the available [OH] in NaOH is present in solution as [${OH}^{-}$] and available to accept protons.
