Because solution pH is a measurement of either [H3O+] or [-OH] concentration, the acidic or
basic nature of the acids and bases used in this experiment can be ascertained by inspecting
just the density (electrostatic) potentials from the products (which contain either H3O+ or –
OH). Using this data, classify the starting materials (HCl, CH3COOH, NH3, NaOH) as acids
or bases and as strong or weak electrolytes. Provide an explanation for each classification.
