lab report about buffers  and the questions

i try to finish this one  but this is difficult  and my lab report kind of weird  please help.

1.Write reaction equations to explain how your acetic acid-acetate buffer reacts with an acidand reacts with a base.2.Buffer capacity has a rather loose definition, yet it is an important property of buffers. Acommonly seen definition of buffer capacity is: “The amount of H+ or OH– that can beneutralized before the pH changes to a significant degree.” Use your data to determine thebuffer capacity of Buffer A and Buffer B.3.Say, for example, that you had prepared a Buffer C, in which you mixed 8.203 g of sodiumacetate, NaC2H3O2, with 100.0 mL of 1.0 M acetic acid.a.What would be the initial pH of Buffer C?b.If you add 5.0 mL of 0.5 M NaOH solution to 20.0 mL each of Buffer B and Buffer C,which buffer’s pH would change less? Explain.
