Question

Write the reaction of concentrated sulphuric acid with analic acid.
​

Answer 1

Answer:

The concentrated sulphuric acid removes water from oxalic acid. So, heating of oxalic acid in presence of concentrated sulphuric acid produces carbon monoxide gas, carbon dioxide gas, and a water molecule

Answer 2

The reaction of concentrated sulphuric acid with analic acid gives Carbon mono and di oxides as well as water.

• The chemical formula of Analic or Oxalic acid is $(COOH)_{2}$. So, when conc. $H_{2} SO_{4}$ is added, the water is removed from the oxalic acid.
• $H_{2} SO_{4}$ + $(COOH)_{2}$  --------> $CO_{(g)}$ + $CO_{2}{(g)}$ + $H_{2}O_{(l)}$
