Question 1

How do you carry out a titration?

Answer 1

1) wash pipette with distilled water and alkali then measure a known volume of alkali into clonical flask
2) Add few drops of acid/base indicator to solution in clonical flask and swirl
3)Rinse burette with distilled water then some acid, allow some acid to pass through tap, then pour acid youre using into tap
4)Record reading on burette, then open tap to release small amount into acid, swirl flask to ensure mixed
5)Repeat 4 until indicator changes colour, shows when alkali in flask has completely reacted with acid added from burette work out volume of acid that has gone into flask
6) Repeat atleast 5 times, discard anomolous results and mean
