I have read somewhere that it is recommended that one add a small piece of tin metal to the stannous chloride solution to extend its life.
Is this true?
Isn't it the reagent grade Stannous Chloride powder is made from a mix of tin metal and hydrochloric acid? so it already has tin in it and would not the excess tin change the chemistry of the solution.
It has been said that the solution must be made in the same way each time so if the addition of tin will not change the readings, is the addition of tin metal an acceptable procedure of making this solution a standard one?
thanks
