Question

why is crystal oxalic acid regarded as good substance for preparation of primary standard solution?

Answer 1

In order to reliably compute the number of moles present from the measured weight and the known molar mass, the main standard is a chemical that can be exactly weighed out in pure forms, such as oxalic acid.

Why is sodium oxalate a good primary standard?

• It's not necessary for the standard solutions used in an acid-base titration to be primary standards.

• because they are readily available in their purest form. Oxalic acid is an example of an acid or base that is used as a primary standard since exact normal solutions can be made from them. This is due to the fact that they are non-hygroscopic and readily available in pure form.

• The oxalic acid standard solution is created and used to standardize sodium hydroxide as it is not a primary standard. At the end of an acid-base titration, the amount of acid and base present is chemically comparable.
