Answers
Answer:
The determination of the strength of a solution of an acid by titration with a standard solution of a base is called acidimetry, whereas when the strength of a solution of an alkali is determined by means of titration with standard solution of an acid, it is termed as alkalimetry.
Aim
To determine the strength of a given solution of sodium hydroxide solution by titrating it against a standard solution of oxalic acid.
Theory
This estimation involves titration of a weak acid that is oxalic acid against a strong base sodium hydroxide and phenolphthalein is the indicator of choice. The reaction between oxalic acid and sodium hydroxide is
(COOH)2 + 2NaOH → (COONa)2 + 2H2O
Since sodium hydroxide is not a primary standard a standard solution of oxalic acid is prepared and used for standardisation of sodium hydroxide.
In acid base titration at the end point the amount of acid becomes chemically equivalent to the amount of base present. In case of strong acid and strong base titration at the end point of solution the solution become neutral.
