Question

Describe the difference between formalin and formaldehyde

Answer 1

Explanation:

Both formalin and formaldehyde have the same chemical formula, which is represented by CH2O.

But there are some differences in their physical state and chemical activities. Basically, formaldehyde is a colorless, water-soluble, flammable gas at room temperature with a sharp, irritating smell.

However, formalin is a liquid, which is prepared by mixing formaldehyde gas and water.

This is the main difference between formalin and formaldehyde.

Generally, a saturated solution of formalin contains about 40% (by volume) or 37% (by weight) of formaldehyde gas and a stabilizer to prevent formaldehyde polymerization.
