REDOX TITRATION

redox titration will take place to a certain extent and strength of KMnO 4 will be of lower value. The mineral acid H 2 SO 4 should be used in the reaction mixture as redox titration takes place under acidified condition. Mineral acid like HCl or HNO 3 should not be used as HCl reacts with KMnO 4 and HNO 3 itself is an oxidizing agent. The use of

Normality Calculator ( Making a solution of solid solute

Normality of a solution is defined as the number of gram equivalent of a solute present per liter of a solution. The gram equivalent is the ratio of molecular weight and equivalence factor. This equivalence factor can be thought as the number of replaceable H + ions in a molecule of an acidic solute or the number of replaceable OH - ions present in a molecule of a basic solute.

How do you calculate the equivalent weight?

Equivalent weights may be calculated from molar masses if the chemistry of the substance is well known: sulfuric acid has a molar mass of 98.078(5) g mol−1, and supplies two moles of hydrogen ions per mole of sulfuric acid, so its equivalent weight is 98.078(5) g mol−1/2 eq mol−1 = 49.039(3) g eq−1.

Potentiometric titration

Remember, that what we calculate is not the end point - but equivalence point. To calculate potential at the equivalence point in redox titration, we can use exactly the same approximation we can use in every other titration type - that reaction proceeded almost to the end, so concentrations of products are given by the reaction stoichiometry.
