One such excipient is Solid W, a metal carbonate (MCO ₃) widely used as an antacid and mineral supplement. According to the United States Pharmacopeia (USP), the acceptable purity range for pharmaceutical - grade metal carbonates lies between 98.0% and 100% o n a dried basis. A certain batch of Solid W is suspected to contain impurities, prompting the quality control laboratory to evaluate its purity through a back -titration procedure. In the analysis, 0.8 g of Solid W was dissolved in 25 cm3 measured volume of 2.0 mol/dm³ hydrochloric acid and solution diluted to 250 cm3 using distilled water. 25.0 cm3 of the resultant solution was titrated with 0.20 mol/dm³ sodium hydroxide solution using phenolphthalein indicator. During the titration, 18.40 cm³ of the sodium hydroxide solution was required to neutralize the unreacted hydrochloric acid. (M = 40, C = 12, O = 16.) Task: Using the information provided, determine the percentage purity of Solid W and decide whethe r the batch meets the USP purity requirement of 98.0 –100%. Item 2: A quality control laboratory received a commercial bleach sample (JIK) used in dental clinics for preparing diluted root -canal irrigation solutions. The bleach contains sodium hypochlorite as the active ingredient, and its true concentration must be checked before it can be diluted to the recommended 0.5% solution. A 10.0 cm³ portion of the JIK sample, with a recorded …
