Vinegar is a chemical used in cooking, cleaning and other common experiences. A 0.1 M solution of vinegar in water has a [H+] of about 1.3 × 10–3. (You may prefer to think of the hydronium ion concentration, [H3O+], as 1.3 × 10–3.)

A. Write the formula for the calculation of pH, and then show each step as you calculate the pH of a 0.1 M solution of vinegar.

B. Is vinegar an acid or a base? Explain how you know.
