Find the approximate hydrogen ion concentration [H+] for each of the following.
(a) Apples: pH = 3.0
(b) Eggs: pH = 7.79
(c) Water (neutral): pH = 7.0
Use the following information. Chemists use the pH (hydrogen potential) of a solution to measure its acidity or basicity. The pH is given by the formula
pH = - log[H+]
where [H+] is the concentration of hydrogen ions in moles per liter.
