Question

Finding the End Point with a pH Electrode

$\mathbf{11}\mathbf{-}\mathbf{33}$What is a Gran plot used for?

Short answer

The gran plot used to locate the end point of the titration by using the data right before the equivalence point

Step-by-step solution

Titration of Diprotic Systems

• Titration of a diprotic acid with a specified quantity of NaOH solution
• Diprotic acid's molecular weight (or molar mass) is expressed in grams per mole.
• You can determine the original acid sample's mass in grams by weighing it.
• The volume of NaOH titrant required to achieve the first equivalence point can be used to calculate moles.

Determine the gran plot used for

Gran plot is used to locate the end point of the titration by using the data right before the equivalence point, for example from $0.8{\mathrm{V}}_{\mathrm{e}}$or $0.9{\mathrm{V}}_{\mathrm{e}}$up to ${\mathrm{V}}_{\mathrm{e}}$.
