Data Sheet Complete the table your observations, and indicate if reaction has occurred there is no evidence of below with box in the table. in the appropriate Metal Cul Nosb ZnNO No No No Reel forms en forums four SoliD No No Ni forms N Based on your observations, list the metals from most active to least active: east Active) (Most Active) Explain your reasoning:

Explanation / Answer

Mg > Zn > Ni > Pb > Cu

Whether or not a metal can replace an another metal from its salt solution , depends solely on its reactivity.

More reactive metals will displace less reactive ones from their salt solution .

In the observation table , you mat notice that copper is unable to replace any metal from the salt, so it is least reactive of all.

The only metal , that could react with all the salts , and replaced their cations is magnesium , so here magnesium is the most reactive metal amongst all.

The rest all other metals that can either replace 2, 3 or 4 are ranked accordingly.
