How do you name chemicals using the -ous or -ic notation?

Question

I have to name the following chemicals for chemistry:
a. Sns
b. SnS2
c. CoCl3
d. CoCl3
e. HgBr2
Hg2Br2
How do you name these chemicals using the -ous or -ic notation

Answer 1

The -ous designation goes to the metal with the lower oxidation state, the -ic designation to the higher oxidation state.

a. Stannous sulfide
b. Stannic sulfide
c. (I think you mean CoCl2 here) Cobaltous chloride
d. Cobaltic chloride
e. Mercuric bromide
f. Mercurous bromide

Answer 3

-ous is always added to the metal when it has a low valency.
-ic is always added to the metal when it has a high valency.

For example, in Hg2Br2, Hg has a valency of 1. Therefore, it's called mercurous bromide.

In HgBr2, Hg has a velency of 2. Therefore, it's called mercuric bromide.

You could also use the new system of naming, where the names become mercury (I) bromide and mercury (II) bromide respectively.

Sns Compound Name

Answer 5

-ic is for the compound with the higher oxidation state (charge) for the metal. -ous is for the compound with the lower oxidation state.

for example:
cupric chloride is CuCl2 and cuprous chloride is CuCl
