WebOct 27, 2024 · The pH measures the number of hydrogen ions (H +) in any solution that contains water and ranges from 0 (acidic) to 14 (base). The lower the pH, the higher the concentration of hydrogen ions. The K a and pK a relate to acids and relate to the acid dissociation constant which shows how likely the acid is to give up its protons. The hydrochloric acid will show pH = 1, and the ethanoic acid will show pH = 3. Only a few drops of sodium carbonate solution and sodium hydroxide solution will be needed to neutralise the acids as the alkaline solutions are eight times more concentrated than the acids. The hydrochloric acid will fizz … See more
