Question

A simple question about solubility >__<

So can you combine BaSO4 and Na2CO3 and form a precipitate??
Only thing I'm just confused about is that BaSO4 is a solid.. so it itself is a precipitate? so it's an insoluble compound..

Answer 1

Well, what you have here is a standard double replacement reaction
BaSO4 (s) + Na2CO3 (aq) --> BaCO3 (s) + Na2SO4 (aq)
So barium carbonate would be the precipiate

*whenever it's asking the formation of a precipitate, you do not consider the solid forms in the reactants, only in the products*

Answer 2

Oh! well the question says.. would you expect to be able to combine solutions of BaSO4 and Na2SO3 and form a precipitate.. so I'm not sure what I'm suppose to expect to happen haha I just thought because BaSO4 is a insoluble.. that my TA was trying to trick me lol

Answer 3

precipitation in the products does not depend on the solid/liquid/gas phase of the reactant, only on their chemical properties :)

Answer 4

Oh! Thank you :)

Answer 5

np! gl in chemistry!
