Q2 / 125 · BITSAT 2017 · Chemistry

Choose the incorrect statement.

A
Sodium borohydride reacts very slowly with cold water
Correct answer
B
Sodium borohydride reacts violently with cold water to give $H_{2} (g)$
C
Solubility of sodium borohydride in water at $25^{0} C$ is $10.05 g / ml$
D
Melting point of sodium borohydride is $500^{0} C$

Solution

Option (b) is the incorrect statement as reaction of ${NaBH}_{4}$ with cold water is very slow. It is not violent. All other are correct statements.

The reaction of sodium borohydride (NaBH₄) with cold water is very slow.

Hence, the correct answer is option: 'B'.
