  5. How did you know that (H^+)(OH^-) = 1E-14?
    And how did you know that (H^+) = 0.30 (Other than knowing that it was given from the questions, how would you know if that was the concentration of the hydrogen ion?)

  6. (a) In aqueous solution there are no HNO3 molecules. Only ions are present.
    (b) (H^+)(OH^-) = 1E-14
    (H^+) = 0.30. Solve for (OH^-)
