8. Lemons contain citric acid. A food scientist collects the juice of 10 lemons and makes the
solution up to 250cm³. He titrates 25 cm³ of this solution with 0.2M sodium hydroxide and
finds that 10.30cm³ of this solution is needed for neutralization. Calculate the concentration
of acid in the lemon solution. (Assume that the formula of citric acid is HX, and that it reacts
in an equimolar ratio with sodium hydroxide).
250 cm³ of hydrogen chloride gas (HCl)) is dissolved in water to make 450 cm³ of solution.
