Question

How can saline hydrides remove traces of water from organic compounds?

Open in App

Solution

Ionic saline hydrides react with water to form metal hydroxide and hydrogen.
$M H + H_{2} O \to A O H + H_{2} (A = N a, C a . . . .)$
On addition to organic solvents, saline hydrides react with water present in them. Hydrogen escapes and metallic hydroxides remains. The dry organic solvent is distilled out.
