Question

Assay of boric acid titration method

Answer 1

Answer:

weigh accurately about 2 gm of boric acid and dissolve in a mixture of 50 ml of water and 100 ml of glycerol previously neutralized to phenolphthalein solution. Titrate the contents of the flask with 1 N sodium hydroxide solution using phenolphthalein as indicator. Repeat the titration for concurrent values.
