-Now you have your 1.0 M NaH2PO4, and the 1.0 M Na2HPO4, 1 M HCl, 1 M KOH made by others in the class, in addition to ultra pure H2O. But your pH meter is not working! Describe how you could use only these available reagents to make a buffer that is 225 mM phosphate at pH 6.5. (5 pts)
-You carry out a reaction in 20 mL of the buffer described in the first part . During the course of the reaction 10 mM (millimolar) base is produced. What will be the resultant pH of the solution upon completion of the reaction?
