At least how many standard solutions would you need to make calibration graph, assuming that the graph is expected to be a straight line? Explain your answer. Do not include the data from distilled water
A compound has 2 ionizable groups, with pKas of 6.2 and 9.5. A 1.0 M solution of this compound (100 mL total volume) is found to have a pH of 6.8. A biochemist adds 60 mL of 1.0 M HCl to this solution. The solution pH is now:
