How do you choose an appropiate indicator for a titration?
Why it is important to use such a small quantity of indicator ina titration?
What is the difference between the end point and equivalencepoint?
Can the End point be used quantitatively? why or why not?
If we rinse the buret with 33% NAOH solution instead of the 0.1Msolution of NAOH and Water , How does this affect the result of ourfirst trial? Assuming this is the only trial, how would this impactthe calculated concentration of NaOH solution?

1 How do you choose an appropriate indicator for a titration To determine the equivalence point the actual point where the reaction has just been completed and refers to the stoichiometric quantities of reactants of a reaction an appropriate indicator should be used The equivalence point should lie between the pH range of an indicator so that the equivalence point can be detected by the change of the color of the indicator For example to determine the equivalence point of the titration of CH3COOH and NaOH phenolphthalein indicator is used Phenolphthalein changes color between 83 and 10 and pH at the equivalence point of the reaction lies in that See Answer
