If a nickel rod embedded in a silver nitrate solution , what do we predict ? explain
Here is a simplified activity series table.
A metal will displace any metal ION BELOW it in the activity series; i.e., Al will displace Cu^2+ but Cu will not displace Al^3+.
2Al + 3Cu^2+ ==> 3Cu(s) + 2Al^3+
Cu^2+ + Al^3+ ==> no reaction.

When a nickel rod is embedded in a silver nitrate solution, a chemical reaction occurs. Let's break down the process and predict what might happen.
1. Nickel and silver nitrate are both electrolytes. When they come into contact with each other in a solution, they can undergo a redox reaction.
2. In the silver nitrate solution, the silver ions (Ag+) are attracted to the negatively charged nickel rod. This attraction occurs due to the difference in electrochemical potentials between the two metals.
3. As the silver ions approach the nickel rod, they gain electrons from the nickel. This electron transfer process leads to the reduction of silver ions to silver metal (Ag).
4. At the same time, the nickel metal (Ni) on the rod loses electrons and is oxidized to form nickel ions (Ni^2+). These nickel ions remain in the solution.
Therefore, we predict that during this process, silver metal will be deposited on the nickel rod, while nickel ions will be dissolved in the silver nitrate solution. This reaction is known as a displacement or redox reaction.
To verify this prediction, an experiment needs to be conducted. You would need a nickel rod, a silver nitrate solution, and a setup to submerge the rod in the solution. After a specific duration of time, you can observe the changes in color and appearance to verify whether silver metal is deposited on the nickel rod.
