A nitric acid solution is found to have a pH of 2.70. Determine [H3O+],[OH-], and the number of moles of HNO3 required to make 5.50L of the
solution.

  • Chemistry -

    a. pH = -log(H^+). Calculate (H^+).
    b. (H^+)(OH^-) = Kw = 1E-14. Solve for OH^-.
    c. M = moles/L soln.
    You have M and L, solve for moles.
