A commonly seen definition of buffer capacity is The get along of H+ or OH that can be neutralized before the pH changes to a significant degree. Use your data to determine the buffer capacity of Buffer A and Buffer B. (Graphically, we can identify buffer capacity by the sudden change to a very steep slope. )Say, for example, that you had on the watch a Buffer C, in which you mixed 8. 203 g of sodium acetate, 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 buffers pH would change less? Explain.
