feso4 is not a primary standard??
hi ppl,
someone plssss help me---why is feso4 not a primary standard?

Feso4, or ferrous sulfate, is not considered a primary standard because it is not a pure substance. It usually contains impurities, which can affect its accuracy and precision in laboratory experiments.
A primary standard is a highly pure substance that can be used to accurately determine the concentration of a solution. Unlike Feso4, primary standards have a known and exact concentration, making them more reliable for use in experiments.
While Feso4 is not considered a primary standard, it can still be used as a standard in laboratory experiments. However, its impurities must be taken into account and corrected for in calculations to ensure accurate results.
Some common alternative primary standards include potassium hydrogen phthalate, sodium carbonate, and potassium permanganate. These substances have known and exact concentrations and are highly pure, making them more suitable for use in experiments.
The concentration of Feso4 can be determined by using a technique called standardization. This involves titrating a solution of Feso4 with a primary standard, and then using the volume and concentration of the primary standard to calculate the concentration of the Feso4 solution.
