How do you determine molarity from titration
To determine molarity from a titration, you need to know the volume and molarity of the titrant (the solution added to react with the analyte), as well as the volume of the analyte solution (the solution being titrated).
1. Write the balanced chemical equation for the reaction occurring in the titration. This will help you determine the stoichiometry of the reaction.
2. Measure the volume of the titrant solution added to reach the equivalence point of the titration. The equivalence point is the point at which stoichiometrically equivalent amounts of reactants have been reached. This is usually indicated by a color change or other observable change.
3. Determine the number of moles of the titrant used by multiplying the volume of the titrant by its molarity. Use the equation: moles = volume (L) × molarity (mol/L).
4. Use the stoichiometry of the reaction from the balanced chemical equation to determine the number of moles of the analyte reacted with the titrant. This step requires knowing the mole ratio between the analyte and the titrant.
5. Divide the number of moles of the analyte reacted by the volume of the analyte in liters to determine the molarity of the analyte. Use the equation: molarity (mol/L) = moles of analyte ÷ volume of analyte (L).
By following these steps, you can determine the molarity of the analyte solution based on the titration results.
