  1. [H_3O^+] = 6.7 × 10^-3M, [OH^-] = 1.0 × 10^-12M
  2. [H_3O^+] = 6.7 × 10^-4M, [OH^-] = 1.0 × 10^-11M
  3. [H_3O^+] = 5.1 × 10^-5M, [OH^-] = 2.0 × 10^-10M
  4. [H_3O^+] = 1.0 × 10^-4M, [OH^-] = 1.0 × 10^-10M
  5. [H_3O^+] = 2.6 × 10^-4M, [OH^-] = 3.8 × 10^-11M
  6. [H_3O^+] = 9.0 × 10^-3M, [OH^-] = 1.1 × 10^-12M
  7. [H_3O^+] = 8.2 × 10^-4M, [OH^-] = 1.2 × 10^-11M
  8. [H_3O^+] = 8.1 × 10^-5M, [OH^-] = 1.2 × 10^-10M
  9. [H_3O^+] = 7.7 × 10^-4M, [OH^-] = 1.3 × 10^-11M
  10. [H_3O^+] = 7.7 × 10^-3M, [OH^-] = 1.3 × 10^-12M
