Oxyanion Nomenclature and Properties

The video tutorial explains oxyanion nomenclature, focusing on naming polyatomic ions with oxygen. It covers the structure of oxyanions, provides examples like carbonate and nitrite, and details the rules for naming them. The tutorial also discusses the use of suffixes and prefixes, such as 'hypo' and 'per', in naming. It includes a section on chlorine-based oxyanions and concludes with a quiz to reinforce learning.

What is an oxyanion?

• A type of metal ion

• A polyatomic ion with oxygen

• A single atom ion

• An ion with a positive charge

Which of the following is an example of an oxyanion?

• Sodium chloride

• Carbonate

• Hydrogen gas

• Iron oxide

How do you determine whether to use 'ate' or 'ite' in naming an oxyanion?

• 'Ite' is used for fewer oxygens, 'ate' for more

• 'Ate' is used for fewer oxygens, 'ite' for more

• It depends on the charge of the ion

• Both are used interchangeably

What does the prefix 'hypo-' indicate in oxyanion nomenclature?

• The same number of oxygens as the 'ate' form

• One less oxygen than the 'ite' form

• A higher charge on the ion

• One more oxygen than the 'ate' form

What is the correct name for an oxyanion with one more oxygen than the 'ate' form?

• Ite- suffix

• Per- prefix

• Hypo- prefix

• Ate- suffix

Which of the following is a halogen-based polyatomic ion?

• Sulfate

• Carbonate

• Bromate

• Nitrate

What is the name of the oxyanion with the formula ClO2-?

• Chlorate

• Chlorite

• Hypochlorite

• Perchlorate

If an oxyanion has the formula BrO3-, what is its name?

• Perbromate

• Hypobromite

• Bromate

• Bromite

What is the correct name for PO4^3-?

• Phosphite

• Phosphate

• Perphosphate

• Hypophosphate

Which element's name is retained in full when naming its oxyanion?

• Carbon

• Chlorine

• Nitrogen

• Sulfur
