You have to prepare a ph 3.50 buffer, and you have the following
0.10M solutions available: HCOOH, CH3COOH,H3PO4,HCOONa, CH3COONa,
and NAH2PO4. Which solutions would you use? How many milliliters of
each solution would you use to make approximately a liter of the
buffer?
The answer on the textbook is 360mL of 0.10M HCOONa and 630mL of
0.10M HCOOH. I just need to know how did they get that answer.
