MODEL RELEASED. Titration experiment. Student using a burette and conical flask to carry out an acid-base titration experiment. This involves addition of an acid to a base,or vice-versa,with the burette (vertical apparatus) used to measure the volume of a known concentration added to a known volume in the conical flask. Colour changes in the indicator used show when the mixture has reached a neutral pH. This then allows known and measured volumes and the known concentration to be used in a calculation of the unknown concentration in the conical flask. The indicators used vary (here,phenolphthalein and methyl red) | |
