Etic acid, CH3CO2H, is the solute that gives vinegar its characteristic odor and sour taste. (Ka was not given in this question)

Part A: Calculate the pH in 0.840 M CH3CO2H.

Part B: Calculate the concentrations of all species present (H3O+, CH3CO2−, CH3CO2H, and OH−) in 0.840 M CH3CO2H.

Part C: Calculate the pH in 0.139 M CH3CO2H.

Part D: Calculate the concentrations of all species present (H3O+, CH3CO2−, CH3CO2H, and OH−) in 0.139 M CH3CO
