When a strip of magnesium metal is placed in an aqueous solution of copper(II) nitrate, elemental copper coats the surface of the magnesium strip and aqueous magnesium nitrate forms. 1. As a reactant, what is the charge on copper?
2. As a product, what is the charge on copper?

1. 2+ ().

2. 0 ().

Explanation:

Hello,

In this case, the described chemical reaction is a redox reaction in fact, since the oxidation states of both magnesium and copper change as shown due to the displacement:

Therefore:

1. Since copper is the cation in the copper (II) nitrate, the (II) means that its charge is 2+ ().

2. Since copper is alone, it means no electrons are being neither shared not given, its charge is 0 ().

Best regards.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
