Which of the following compounds would be the most suitable for making a stock solution of Pb2+ ion for calibration purpose in AAS?

Which of the following compounds would be the most suitable for making a stock solution of Pb2+ ion for calibration purpose in AAS? Correct Answer Pb(NO<sub>3</sub>)<sub>2</sub>

Pb(NO3)2 be the most suitable for making a stock solution of Pb2+ ion for calibration purposes in AAS.

Important Points What is Stock Solution?

  • The term "Stock Solution" is commonly used to confer with a concentrated solution, from that one will dilute into a working concentration of the solution.
  • Stock solutions are used to save preparation time, conserve materials, reduce space for storing, and improve the accuracy with that working lower concentration solutions are prepared.

Key Points Pb(NO3)2 - Lead Nitrate or Lead dinitrate

  • Lead nitrate could be a white crystalline solid.
  • The material is soluble in water.
  • It's incombustible however it'll accelerate the burning of flammable materials.
  • It is white or colorless semitransparent crystals.

Additional Information

  • Atomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) may be an electroanalytical procedure for the quantitative determination of chemical components exploitation the absorption of optical radiation (light) by free atoms within the aerosolized state.
  • Atomic absorption spectroscopy relies on the absorption of light by free metallic ions.

A chemical solution appears green when the salt concentration is 8 grams per litre (gpl) and red when it is 10 gpl. Pure water was added to the solution of 1 litre of 15 gpl solution till it turned green. Then 125 ml of the green solution is taken out and x grams of salt is added to the green solution to make it red. Another 500 ml of the final solution was taken out and y litres of green solution is added to get a resultant solution of concentration 9.6 gpl.  Assume adding salt doesn’t change its volume and find the ratio of x and y.
