Single Replacement Reactions
« on: October 05, 2013, 05:24:31 PM »
Do precipitates ever form in single replacement reactions?

For example, if the reaction was Ca + ZnSO4  :rarrow: Zn + CaSO4, would the CaSO4 be considered aqueous or a precipitate?

Also, are the halogens F2, Cl2, Cr2, and I2 more reactive than any other elements?

Sorry i forgot to add the condition that ZnSO4 is in solution.

What is CaSO4 solubility?

CaSO4 is insoluble, but in a single-replacement reaction is it still considered as a precipitate?

Why should the kind of reaction matters? Can it be soluble if produced in one kind of reaction and insoluble when produced in other? Substance properties don't depend on the synthesis route.
