Hello Everyone.
My question is regarding Chemistry, I have passed earlier to a question found in Paper 11 O/N 2011 Question 11. The Idea there had stated that Sodium was the metal that CANNOT be used in electroplating by using an Aqueous solution.Why is it sodium? Why couldn't it be Silver? Is it because it would react or it has a more reactivity in the reactivity series.

Just wanted to double check
Thanks you in advance,

while the correct answers are:
1, 9, 21, 29, 40
