    1.Given the molar concentration of hydrogen ion [H+] = 6.2 x 10 -7, calculate the concentration of hydroxide ion.

    2.Given the molar concentration of hydroxide ion [OH -] = 4.6 X 10 -13, calculate the concentration of hydrogen ion.

    3. In 1 mL of water there are 3 X 1022 molecules of H2O. How many hydrogen ions are in 1 mL of water (Hint: In 1 billion water molecules, only 2 are ionized).

    4. What is the pH of a 0.25 M NaOH solution?

    5. A Rolaids tablet contains calcium carbonate, which neutralizes stomach acid. If 44.55 mL of 0.488 M hydrochloric acid is required to neutralize one tablet, how many milligrams of calcium carbonate are in a Rolaids tablet?

    CaCO3.(s) + 2 HCl(aq) ® CaCl2(aq) + H2O(l) + CO2(g)
