...approaching the equivalence point? Discuss the importance of the addition os smaller volumes of titrant when approaching the equivalence point
 
1)if you overshoot the endopint, the color will not change. once you reach the endpoint, the indicator will give its 'telltale color' specific for itself. if you overshoot the endopint, the indicator will not change color and you will not know how much extra titrant you have added.

if you go beyond the equilvalence point, you would have to back-titrate by adding more of the solution being titrated.

2)if you are very very close to the endpoing, yet the indicator is not the color expected at the endpoint, one needs to be very careful about the volume fo titrant to be added.

3)fractions of drops can still be accounted for with a burette. it takes practice and the solution needs to be sitrred continuously so that the titrant has 'access' to all of the ions/chemical(s) being titrated.
