Answer to Question #71442 in Organic Chemistry for Christopher Rodriguez

Question

To determine the concentration of citric acid, you will need to titrate this solution with 0.100 M NaOH. You are given a 1.00 M NaOH stock solution and will need to make enough 0.100 M NaOH to perform 3 titrations. For each titration, you will use 35.0 mL of 0.100 M NaOH solution.

(a) Calculate the total volume (in mL) of the diluted solution you will need to prepare for the 3 titrations.
mL
(b) Determine the minimum volume (in mL) of 1.00 M NaOH stock solution needed to prepare the 0.100 M NaOH solution.
mL

Answer 1

(a): the total volume of the diluted solution: 35.0 ∙ 3 = 105.0 mL
(b): the minimum volume of 1.00 M NaOH stock solution: 105.0 / 10 = 10.5 mL
