Question

Raney Nickel is finely divided nickel obtained by digesting alloys of $Ni/Al$ over $NaOH$.

• A. True
• B. False

Answer 1

The correct option is A True

Raney nickel is a fine-grained solid composed mostly of nickel derived from a nickel aluminum alloy

The alloy is treated with a concentrated solution of sodium hydroxide. The simplified leaching reaction is:

$2Al+2NaOH+6H_{2}O\to 2Na\left[Al{\left(OH\right)}_4\right]+3H_2$

After this process, leaching is done to form raney nickel which is powder and spongey.

Given statement is true.
