How much nitric acid does vinegar have?

Answer 1

Vinegar is the household name for a chemical compound known as Acetic Acid. The kind of vinegar you buy from the grocery store is typically composed of about 5% acetic acid and 95% water (by weight), giving an acid concentration of .83 M.

However, this doesn't completely answer the question because some acids are stronger than others. Chemists measure acidity by the concentration of free-floating protons released by the acid. The proton concentration of commercial vinegar is 3.9 x 10-2 M, giving it a pH of 2.4 (low pH = higher acidity). For comparison, lemon juice has an approximate pH of 2.0 and Coca-Cola has a pH of 2.6.

So vinegar has a little more acid than coke and a little less acid than your average lemon.

Answer 2

Vinegar shouldn't have any nitric acid. Vinegar contains acetic acid (also called ethanoic acid) CH3COOH, and table vinegar is often ≈5% acetic acid dissolved in water. Natural vinegar may contain trace amounts of other acids, but these are unimportant to its definitive composition.

I recommend looking at Wikipedia or another online encyclopedia to answer a question like this.

Answer 3

Vinegar is about 5 to 10 % aqueous solution of acetic acid.

Answer 4

There is 4 to 5% acetic acid (ethanoic acid) in natural, food grade vinegar

Answer 5

Titrate against a base such as NaOH, or use NIR spectroscopy if you have one available...
