An acetate buffer solution is prepared by combining 50. mL of 0.20 M acetic acid, HC2H3O2(aq), and 50. mL of 0.20 M sodium acetate, NaC2H3O2(aq). A 5.0 mL sample of 0.10 M NaOH(aq) is added to the buffer solution. Which of the following is a correct pairing of the acetate species present in greater concentration and of the pH of the solution after the NaOH(aq) is added?A. HC2H3O2 pH < 4.7B. HC2H3O2 pH >4.7C. C2H3O2- pH < 4.7D. C2H3O2- pH > 4.7
can anyone write what is happening in this reaction by writing all the equation???
