7 g of iron is put in copper sulphate solution, and all of it reacts: Fe + CuSO₄ → FeSO₄ + Cu.
Contributed by StemPy LabTry it on paper first. A hint, the key idea and the worked solution are here when you need them.
of iron is put in copper sulphate solution, and all of it reacts: . What mass of copper is displaced? Use and .
Need a reminder? The key ideaShow
Metals form basic oxides; aluminium and zinc oxides are amphoteric. Reactivity with water: K, Na violent; Ca cold water; Mg hot water; Al, Zn, Fe steam; Pb, Cu, Ag, Au none. Metals above hydrogen give hydrogen with dilute acids. A metal displaces those below it from their salt solutions.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. Moles of iron. .
Step 2. Copper. .
Answer: about of copper.
