Acid Alkali Titration

Titration 1Acid Base titrationAS LevelTo compare the results of a simple strong acid-strong base titration using different indicatorsYou are provided with the following aqueous solutions

FA 1Hydrochloric acid of concentration 0.05 mol dm-3 FA 2aqueous sodium hydroxide

A. Titrate 25.0cm3 of FA 2 against FA 1, using methyl orange as indicator. Carry out the titration as many times as you thing necessary to achieve accurate results.

B. Repeat the experiment, using phenolphthalein as an indicator .
