Oxyacid Naming and Structure

In this video, Michael from Concord Chemistry explains how to name oxyacids, which are acids containing oxygen. The video covers the general form of oxyacids, naming rules, and exceptions. It provides examples of converting chemical formulas to names and vice versa. The video concludes with a summary and offers additional resources for further learning.

What is the general structure of an oxyacid?

• H, sulfur, and oxygen

• H, nitrogen, and oxygen

• H, carbon, and oxygen

• H, another element, and oxygen

When naming an oxyacid, what suffix is used if the polyatomic ion ends in '-ate'?

• -ite

• -ate

• -ic

• -ous

Which of the following is an exception to the standard naming rules for oxyacids?

• Bromate

• Chlorate

• Sulfate

• Nitrate

What is the correct name for HNO2?

• Nitrate acid

• Nitric acid

• Nitrous acid

• Nitrite acid

What is the chemical formula for phosphoric acid?

• H2PO4

• H3PO4

• H3PO3

• HPO4

How do you determine the subscript for hydrogen when converting phosphoric acid to its formula?

• By using the molecular weight

• By using the atomic number of phosphorus

• By counting the number of oxygen atoms

• By balancing the charges

What is the original polyatomic ion for chlorous acid?

• Chlorate

• Chlorite

• Chloride

• Hypochlorite

What suffix is used for an oxyacid if the polyatomic ion ends in '-ite'?

• Replace '-ate' with '-ide' and '-ite' with '-ic'

• Replace '-ate' with '-ous' and '-ite' with '-ic'

• Replace '-ate' with '-ic' and '-ite' with '-ous'
