1. you start with 0.020 l of 0.050 m benzoic acid (ka = 6.28*10-5).
a) what is the initial ph?
b) what is the ph if you add 5.0 ml of 0.0010 m koh?
c) how much volume of the 0.0010 m koh would you need to add to get to the equivalence point?
d) what is the ph at the equivalence point?
e) after the addition of 25 ml of 0.050 m koh, what is the ph?
f) how much volume of the 0.050 m koh would you need to add to get to the equivalence point? 9) [what type of indicator would you choose to follow this titration? what change do you expect to see at the equivalence point? ] h) (sketch a curve of volume of 0.050 m koh added to ph and mark the different points of interest. at what volumes of koh added do you have a buffer solution? ]
