4. Given the following equation : H2S (aq) + H2O (1) E→ H3O* (aq) + HS' (aq) For each of the following changes at equilibrium, indicate whether the system shifts to the left or to the right : a. Removing some H2S (aq) b. Adding more H3O* (aq) 5. A solution has [OH] = 2.4 x 1011 M. Calculate [H30*] and determine whether the solution is acidic, basic, or neutral 6. What is the pH of a solution with [OH'] = 1.7 x 10-3 M ? 7. Calculate [H3o*] of a solution with a pH of 5.5 8. A 15.0 mL sample of H2SO4 solution is titrated with 24.0 mL of 0.245 M NaOH solution. What is the molarity of the H2SO4 solution? H2SO4 (aq) + 2 NaOH (aq) → 2 H2O (1) + NazSO4 (aq)
