Below shows 3 displacement reactions involving metals and solutions of metal nitrates.
Use this information to find the order of reactivity of the 4 metals, with the most reactive. I know their order but how do you use the information? How does the info help with the order of reactivity?
It tells which metal replaces which metal. If M displaces the ion of metal X then M goes above. If M does not displace X, M goes below. For example, Cu displaces Ag^+; therefore, Cu is above Ag in the activity series. Pb is above Cu. Zn is above Pb. You can make a table of these four.
