Question

Each of the following compounds contains a metal that can exhibit more than one ionic charge. Name these compounds:

a. NiCO₃

b. MoO₃

c.Co(NO₃)₂

d. V₂O₅

e. MnO₂

f. Fe₂O₃

Step-by-Step Solution

Verified

Answer

a. Nickel Carbonate

b. Molybdenum trioxide

c. Cobalt nitrate

d. Vanadium (V) oxide

e. Manganese (IV) oxide

f. Iron (III) oxide

1Step 1: Understanding the concept of ionic charges.

Generally, a large number of metals exhibit the property of showing multiple positive charges or ionic states. This property depends upon the entity forming a bond with the metal. The metal loses its electron according to the requirement of electrons by the other entity.

For example, Iron (Fe) can show two ionic states, i.e., +2 and +3

2Step 2: Determining the names of the compounds

(a)NiCO₃= Nickel Carbonate

This is an ionic form of Ni²⁺andCO₃^2-

(b) MoO₃=Molybdenum trioxide

Molybdenum trioxide is the ionic form of Mo ⁶⁺three O^2-ions.

Cobalt nitrate is an ionic form of Co²⁺and two(NO₃)^-ions.

(d) V₂O₅= Vanadium (V) oxide

(e) MnO₂=Manganese (IV) oxide

(f) Fe₂O₃=Iron (III) oxide
