Select the incorrect statement.

Options

  1. AN a O H can be stored in a vessel made of aluminium
  2. BH N O 3 can be stored in a vessel made of Be/Aluminium alloy
  3. CH F can be stored in a vessel coated of wax
  4. DH F attacks glass

Correct answer

A. N a O H can be stored in a vessel made of aluminium

Step-by-step solution

2 A l + 2 N a O H + 2 H 2 O → N a A l O 2 + 3 H 2 Aluminium dis Solutionves in aqueous alkali, thus N a O H cannot be stored in a vessel made of aluminium
