Oxidation Numbers and Chlorate Ion

The video tutorial explains how to determine the oxidation number of chlorine in the chlorate ion (ClO3-). It begins by discussing the oxidation numbers of oxygen and chlorine, and how they sum up to the charge of the ion. The video demonstrates the calculation process, showing that the oxidation number of chlorine is +5. An algebraic method is also presented to verify the result. The tutorial concludes with a summary of the findings.

What is the oxidation number of oxygen typically considered to be?

• 0

• -2

• +1

• -1

How many oxygen atoms are present in the chlorate ion (ClO3-)?

• 1

• 2

• 3

• 4

What is the total oxidation number for the three oxygen atoms in ClO3-?

• -3

• -6

• -2

• -1

What is the oxidation number of chlorine in the chlorate ion (ClO3-)?

• +3

• +5

• +1

• +7

In the equation x - 6 = -1, what does x represent?

• The oxidation number of oxygen

• The total charge of the ion

• The oxidation number of chlorine

• The number of oxygen atoms

What is the result of adding 6 to both sides of the equation x - 6 = -1?

• x = 5

• x = -5

• x = 6

• x = -6

What is the final confirmed oxidation number of chlorine in ClO3-?

• +5

• +3

• +7

• +1
