A fruit juice contains an unknown percentage of citric acid. During a titration 33.50 cm³ of 0.0102 M sodium hydroxide is required to neutralise the citric acid in 50.0 cm³ of fruit juice. The unbalanced reaction equation is given in Figure 10. Citric acid is a triprotic acid – it can donate three H⁺ ions in aqueous solution. You can assume that the density of the fruit juice is the same as that of water. What is the percentage of citric acid in the sample? [Round the answer to three decimals. Do not type in the percentage sign. Use a decimal point.]
