Problem: What is the correct name for the compound CoCl2?

FREE Expert Solution

We’re being asked to name CoCl2. The rules for naming binary ionic compounds are as follows:


1. The metal keeps its name and is named and written first.

– For transition metals, we use Roman numerals to denote its charge.


2. The nonmetal keeps its base name but has its ending change to –ide.


We can see that the metal in the ionic compound is Cobalt (Co), which is a transition metal. 

This means it has several possible charges.
