How To Work Out If Precipitate Is Formed

how to work out if precipitate is formed

What can be used to determine if a compound forms a

If you mix together two solutions containing barium ions and sulphate ions and the product of the concentrations would exceed the solubility product, you get a precipitate formed. Enough solid is produced to reduce the concentrations of the barium and sulphate ions down to a value which the solubility product allows.

How to calculate the amount of precipitation that forms in

Another way is to weigh out 50 g of the salt, dissolve it in water, then add a large excess of the soluble salt BaCl2, to make the a precipitate of BaSO4, filter it, wash, dry, and weigh it. From the number of moles, you will fiond the moles of Al2(SO4)3 and hence its Mr. The result will only be accurate to around 2%, but the mass spec method correct to 0.00001%.
