Ferrous Oxide Naming and Charges

This video tutorial explains how to write the formula for ferrous oxide, focusing on the older Stock naming system. It clarifies the meaning of 'ferrous' as iron with a 2+ ionic charge and contrasts it with 'ferric' for a 3+ charge. The tutorial emphasizes the importance of balancing ionic charges to form a neutral compound, resulting in the formula FeO. It also compares the old naming system with the newer one, where ferrous oxide is referred to as iron(II) oxide.

What does the 'ous' suffix indicate in the Stock naming system?

• A higher ionic charge

• A lower ionic charge

• A neutral charge

• No charge

In the context of iron, what ionic charge does the 'ic' suffix represent?

• Fe2+

• Fe1+

• Fe3+

• Fe4+

What is the ionic charge of oxygen in ferrous oxide?

• 2+

• 3-

• 2-

• 1-

What is the chemical formula for ferrous oxide?

• FeO

• Fe2O3

• Fe3O4

• FeO2

How do the charges of Fe2+ and O2- combine in ferrous oxide?

• They do not combine

• They add up to zero

• They add up to a negative charge

• They add up to a positive charge

What would ferrous oxide be called in the newer naming system?

• Iron(III) oxide

• Iron(I) oxide

• Iron(IV) oxide

• Iron(II) oxide

Why is it important to understand the ionic charges of iron?

• To determine the melting point

• To find the density

• To correctly name the compound

• To predict the color of the compound
