The volumes between successive equivalence points in the titration of a polyprotic acid are theoretically equal. Consider again the titration of citric acid (H3C6H5O7) as in question 1 of the Pre-laboratory Questions where a titration required 15.3 mL of 0.180 M NaOH to reach the first equivalence point. How many mL of this base would be required so that the titration solution was essentially a solution of sodium citrate (Na3C6H5O7)?
Pre Lab Question 1: Titration of 22.0 mL of a solution of citric acid (H3C6H5O7) required 15.3 mL of 0.180 M NaOH to reach the first equivalence point of the titration. What is the concentration of the citric acid solution?
Answer: 0.125M
