The purpose of this experiment of titration was to determine the unknown concentration of sodium hydroxide. To do this I made up a Primary standard (the Sodium Hydroxide) so this could standardise the concentration of the Hydrochloric Acid. We use Sodium Hydroxide for Our primary standard as it had a relatively large molecule mass and it's very stable it tend to be used to standardise aqueous acids (hydrochloric,sulphur and nitric. ) Hydrochloric acid then became a secondary standard which was ...
