A 50.0-g piece of metal at 60.0oC is placed in 200.0 g of water at 22.0oC contained in a coffee-cup calorimeter. The metal and water come to the same temperature at 32.5oC. (S. H. Of water is 4.18 J g-1 K-1)

Calculate the expected ph values of the buffer systems from the experiments (a,b,c,d), using the henderson- hasselbalch equation, ph-pka+log[a-]/[ha]. use for pka values carbonic acid= 6.37, and acetic acid= 4.75.
