A. calculate the molarities of HC2H3O2 and NaC2H3O2 in the buffer solution you will prepare for this experiment 

B. calculate the theoretical pH of this buffer solution 

C.write the chemical equation for the reaction that occurs when you add 0.10M NaOH solution to the HC2H3O2-NaC2H3O2 buffer solution

D. Briefly explain why the concentrations of the HC2H3o2 and C2H3O2- ion change when you add .1M HCL solution to the HC2H3O2-NaC2H3O2 buffer solution. write an appropriate chemical equation showing changes that occur

Thank you, anything will help!! :)
