Determination of soluble sulphate by gravimetric analysis
« on: March 09, 2008, 09:08:55 AM »
In determination of soluble sulphate by gravimetric analysis, it is beneficial to precipitate the sulphate with an aged BaCl2 solution.

Anyone explain why an AGED BaCl2 should be used instead of a normal one?

Any other steps, like "aged, then filtered" BaCl2 in the procedure?

Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.
