In a water solution, how do acids differ from bases? a. acids form hydrogen ions (h+), while bases form hydroxide ions (oh–). b. acids turn litmus blue, while bases turn litmus red. c. acids form salts, but bases do not. d. hydrogen ions (h+) remain dissolved, but hydroxide ions (oh–) do not.

Water molecules are composed of two hydrogen atoms bonded to an oxygen atom. In liquid water, the molecule can dissociate into positive hydrogen ions (H+) and negative hydroxide ions (OH-). The correct answer in this case is (a), since acids form hydrogen ions, while bases form hydroxide ions. The balance of these ions determines the pH of a liquid.
