Question

What is / are the suffix used for all oxy-acids?

• A. Suffix of -ic
• B. Suffix of -ous
• C. Suffix of -ic and -ous
• D. None of the choices

Answer 1

The correct option is C

Suffix of -ic and -ous

For all oxy-acids the suffixes used are either -ic or -ous.

Complex acid compounds have oxygen in them. For any acid with a polyatomic ion, the suffix “-ate” from the ion is replaced with “-ic.”

Similarly, polyatomic ions with one fewer oxygen have the suffix “-ous”
