10) You want to create a buffer using phosphoric acid and SodiumDihydrogen Phosphate. what is the best pH at which to make thebuffer? using that pH and a concentration of 1M. Determine themolar concentrations of each component (acid and base) needed tomake the buffer. If you need 100mL of the buffer, how many mL of2.5 M phosphoric acid will you need? How many grams of the SodiumDihydrogen Phosphate do you need?
11) using the buffer you created in problem 10 calculate thechange in pH if you add 1 mL of 0.50M HCl to the buffer.
12) using the buffer you created in problem 10. calculate thechange in pH if you add 2 mL of 0.50 NaOH to the buffer.
