So, there are actually two main chemical formulas involved. The molecular formula for water is H2O. The structural formula for acetic acid is CH3COOH.
Vinegar is a naturally-occurring liquid that contains many chemicals, so you can't just write a simple formula for it. It is approximately 5-20% acetic acid in water. So, there are actually two main chemical formulas involved. The molecular formula for water is H2O. The structural formula for acetic acid is CH3COOH. Vinegar is considered a type of weak acid. Although it has an extremely low pH value, the acetic acid doesn't completely dissociate in water.
