Find the approximate pH of each of the following.
(a) Blood: [H+] = 3.98 × 10-8 = 0.0000000398
(b) Beer: [H+] = 6.31 × 10-5 = 0.0000631
(c) Vinegar: [H+] = 6.3 × 10-3 = 0.0063
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.
