What is a titration reaction in acid-base chemistry?
A titration reaction is used to calculate the conentration of an acid or alkali. The two solutions are combined, one of known and one of unknown concentration. When combined the hydrogen ions from the acid and the hydoxide ions from the alkali react to form water, this is a neutralisation reaction.
A known volume of alkali is placed in a conincal flask, with a suitable single indicator. A burette, held be a clamp stand, is filled with the acid and placed above the flask. The acid is slowly combined with the alkali until the point at which the acid completely neutralises the alkali and the indicator changes colour.
The volumes of the two solutions, which neutralised completely, and the known concentration of one of the acid/alkali is used to calculate the concentration of the other.
