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.
