Question

 You are asked to make the 4.5 pH buffer from question the previous question.  
a. From the list of Acids and conjugate bases attached which pair would you pick. 
b. You are asked to make a 2M stock solution of the Buffer, how many grams of each acid 
and base would you need to make a 1000mL stock.

c. For the experiment, the final concentration of the buffer should be 50mM. How many 
mL of your stock would you need to make 2L. Hint: M1V1=M2V2
