What is the minium purity of a substance used to prepare a primary standard?
The minimum purity of a substance used to prepare a primary standard should be at least 99.8% to ensure accuracy and reliability of the standard solution. Impurities in the substance can lead to errors in the final concentration calculations.
What is a standard solution and how is it used in titration?
A standard solution is a solution with a known concentration of a substance. In titration, a standard solution is used to determine the concentration of another substance by reacting the two solutions until a chemical reaction reaches completion. The volume of the standard solution needed to react completely with the unknown solution is used to calculate the concentration of the unknown substance.
