Title: Single Replacement Reactions
Post by: dchai56 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.
