CH₂-COOH Citric acid has the formula HO-C-COOH I CH₂-COOH CH2–CDD - Na* + HD-C-CDD- Na CH₂-COO- COO-Na A 25.0 mL sample of a concentrated citrus fruit cordial component (e.g. for lime juice), used in the food & drinks industry, was diluted to 250 mL in a graduated volumetric flask. A 25.0 mL sample of this diluted solution, required, on average, 22.5 mL of a standard 0.100 molar sodium hydroxide solution using phenolphthalein indicator for the titration end-point. A) 0.0075 Assuming all the acid in the cordial was citric acid, calculate the concentration of the acid in g/mL in the original solution. B) 0.576 D and is tribasic acid, forming the tri-sodium salt on complete neutralisation with sodium hydroxide. 1.44 0.00225
