Choose the incorrect statement.

Choose the incorrect statement.

Options

  1. ASodium borohydride reacts very slowly with cold water
  2. BSodium borohydride reacts violently with cold water to give H2(g){H}_{2} ( g )
  3. CSolubility of sodium borohydride in water at 250C{25}^{0}C is 10.05g/ml10. 05g / ml
  4. DMelting point of sodium borohydride is 5000C{500}^{0}C

Correct answer

B. Sodium borohydride reacts violently with cold water to give H2(g){H}_{2} ( g )

Step-by-step solution

Option (b) is the incorrect statement as reaction of NaBH4{NaBH}_{4} with cold water is very slow. It is not violent. All other are correct statements. The reaction of sodium borohydride& (NaBH_{4})& with cold water is very slow.&
