Question

3. Water of crystallization present in oxalic acid is/are..........​

Answer 1

Answer:

water of crystallization present in oxalic acid is 5.17 percent

Answer 2

Two water of crystallization is present in oxalic acid.

• Oxalic acid is a weak acid having the formula $(COOH)_2$.
• It has two COOH groups in its structure.
• The dehydrated oxalic acid does not contain water of crystallisation.
• But the formula of hydrated oxalic acid is $(COOH)_2.2H_2O$.
• Thus we can see that hydrated oxalic acid has two moles of water of crystallisation.
