Question

Choose the correct statements from the folllowing.
(I) NaOH crystals are deliquescent in nature
(II) NaOH is corrosive in nature
(III) NaOH is soluble in water to give strong alkaline solution.
(IV) NaOH is soluble in water to give an acid solution.

• A. (I) and (II)
• B. (I), (II) and (III)
• C. (I) and (III)
• D. (I), (II), (III) and (IV)

Answer 1

The correct option is B (I), (II) and (III)

NaOH crystals are deliquescent in nature.
NaOH is corrosive in nature.
NaOH ionise completely in water as $N{a}^{+}$ and $O{H}^{-}$.
Because of the $O{H}^{-}$ ions in the solution it will be strongly alkaline.
Hence, statement (I), (II) and (III) are correct.
