Aqueous potassium sulfate can be prepared by titrating dilute sulfuric acid against aqueous potassium carbonate. What conclusion can e drawn from here? And explain why is it so.
H2SO4 + K2CO3 ==> K2SO4 + H2CO3
(and H2CO3 breaks down to form H2O and CO2).
If K2SO4 is to form from this reaction, the other product must be (a) a solid(insoluble) (b) a gas (c)slightly ionized substance. It isn't a solid therefore it must be b or c. If be forms it is transient and we see a gas being evolved; therefore, c is the reason the reaction proceeds.
