Am blanking out a bit as it is late hehe, so thought I'd quickly ask for advice before spending 30 mins looking for info only to forget what I was looking for.
Ok, here is a Q & A:
The correct statement concerning 50 mL of basic solution composed of 0.2 M NaH2PO4 and 0.2 MNa2HPO4 is the pH of the solution will not change with the addition of 20 mL of water.
Answer: This solution is a buffer. The pH of a buffer does not change with the addition or removal of water.
Ok why is the solution a buffer again?
