- pH expresses the molar concentration of hydronium ions in an aqueous solution on a logarithmic scale. (Note that it is common to use the hydrogen ion, H*, to represent the hydronium ion, H3O+.) pH = -log[H3O+] [H3O+] = 10-PH As pH decreases, acidity increases. As pH increases, acidity decreases. • Acidic solution: pH 7 Part A - Calculating pH Submit [H₂0+] 1 Acidic pH 01 10¹ 102 103 104 105 106 107 108 109 10-10 10-11 10-12 10-13 10-14 stomach acid 3 wine lemon tomatoes juice vinegar, black soft drinks, coffee beer 6 Neutral urine milk 7 human blood pure water sea- water baking soda 10 11 12 13 14 milk of magnesia house- hold ammonia oven cleaner Basic household bleach Adapted from Biological Science by Freeman ©2008 Pearson Education, Inc.
