Imagine that you go into the lab and perform a titration. You measure 50 mL of your analyte and add it to an Erlenmeyer flask. To this you add 3 drops of an indicator solution that will change color from clear to blue. Into your burette you add 50 mL of a 2.5 M standard solution that reacts with your analyte in a 1:1 mole ratio. You do the titration and find that after you have added 32 mL of standard, the solution in your Erlenmeyer flask turns blue.What volume of analyte did you start with

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
