Since we started with 50 mL of the titrant and 32 mL of a 2.5 M standard solution. Using the dilution equation M2 = 2.5 M × 32 mL/50 mL
Titration is a means of determining the concentration of a solution by using another solution of known concentration. The solution of known concentration is called the standard solution.
The titrant is the solution in the flask. We started with 50 mL of this solution, then we added 32 mL of the standard solution. Using the dilution formula;
M2 = 2.5 M × 32 mL/50 mL
