Preparation and Standardization of 0.1 M Lead Nitrate

Preparation and standardisation of 0.1 M Lead Nitrate solution using Disodium Edetate and Xylenol Orange mixture as indicator used in chemical analysis of pharmaceutical ingredients.

Lead Nitrate Solution Preparation

  • Dissolve 33.12 g of lead nitrate in sufficient water to produce 1000 ml.
  • Standardize the solution in the following manner.

Lead Nitrate Solution Standardization

  • Pipette 50.0 ml of the solution into a flask.
  • Add 50 mg of xylenol orange mixture and sufficient hexamine to produce a violet-pink color.
  • Titrate with 0.1 M disodium edetate to a lemon yellow endpoint.
  • 1 ml of 0.1 M disodium edetate is equivalent to 0.03312 g of Pb(N03)2.
