Question

​​Differentiate between soap solution,ethanol,ethanoic acid,on the basis of reaction with sodium metal.

Answer 1

1. Soap solution contains water and sodium metal reacts with water to undergo an exothermic reaction shown below:


2 H₂O +2 Na $\to$ 2 NaOH + H₂

2. Ethanol also undergo an exothermic reaction with sodium metal to form base and hydrogen gas:

2 C₂H₅OH + 2 Na ​$\to$2 C₂H₅ONa + H₂

3. Ethanoic acid reacts with sodium metal to give Sodium Acetate and Hydrogen gas. The reaction is :

2 CH₃COOH + 2 Na $\to$ 2 CH₃COONa + H₂
