Based from the given problem, What is the percentage purity of the tartaric acid (C4H6O6)? * Part 2: Assay of tartaric acid (Jenkin's Guantitafive Pharmaceutical Chemistry by Knevel, pp.108) Place about 2 g of tartanic acid previously dried and accurately weighed in a conical tiask. Dissolve it in 40 mi of water. add a few drops of phenophthalein TS, and titrate with 1 N sodium hydroxidel Each mi of 1N hydroxide is equivalent to 75 mg of tartaric acid. *Note: Volume of sodium hydroxide was observed at 26.5 ml USP Requirement: Not less than 99.7 and not more than 100.5%)

Based from the given problem, What is the percentage purity of the tartaric acid (C4H606)? * Part 2: Assay of tartaric acid (Jenkin's Quantitative Pharmaceutical Chemistry by Knevel, pp.108) Place about 2 g of tartanic acid previousty dried and accurately weighed in a conical fiask. Dissolve it in 40 ml of water. add a few drops of phenoiphthalein TS, and titrate with 1 N sodium hydroxidel Each ml of IN sodium hydroxide is equivalent to 75 mg of tartaric acid. *Note: Volume of sodium hydroxide was observed at 26.5 ml USP Requirement: Not less than 99.7 and not more than 100.5%)
