- 36. Titrating a 10.00 mL aliquot of 0.150 M NaOH with 0.120 M HCl will require a. 8.00 mL b. 0.18 mL c. 18.00 mL d. 12.50 mL9. Chloride in a brine solution is determined by the Fajans method. A 10.00-mL of solution is titrated with 15.00 mL of a standard 0.1100 M AgNO3 solution. A blank titration is conducted, requiring 0.50 mL of the standard AgNO3 solution. Calculate the concentration of chloride in the brine solution. A. 5.00 M B. 5.32 M C. 5.65 M D. 5.80 MYou have a solution of a standardized titrant of 0.01254 M and a sample that approximately has a molarity of 0.48 M. What dilution do you have to do to spend approximately 15 mL of titrant if you have 25 mL and 10 mL pipettes to take the diluted sample and value it ? Solution: With the 10 mL pipette, the sample should only be previously diluted 1:25, with the 25 mL one 1:64. Therefore, 10 mL of the sample can be taken and made up to 250 mL.
