Question

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

a. Cr₂O₃

b. FeCl₂

c. CrO₃

d. TiCl₄

e.CoO

f. MoS₂

Step-by-Step Solution

Verified

Answer

a. Chromium (III) oxide

b. Iron (II) chloride or ferrous chloride

c. Chromium trioxide

d. Titanium tetrachloride

e. Cobalt (II) oxide

f. Molybdenum sulfide

1Step 1: Understanding the concept of ionic charges.

Generally, many 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) Cr₂O₃- Chromium (III) oxide

(b)FeCl₂- Ferrous chloride

(d) TiCl₄- Titanium tetrachloride

(e) CoO- Cobalt Oxide

(f)MoS₂- Molybdenum sulfide
