Calculate the ph of a buffer solution made from 0.10 m nh3 and 0.10 m nh4cl
salt. kb = 1.8 x 10-5

b. calculate the ph of the buffer in part a, after 12 ml of 0.20 m hcl is added to 125 ml
of the buffer in part a.

c. calculate the ph when 12 ml of 0.20 m hcl added to 125 ml of water. how does
the ph compare to the ph found in part b?
