Oxidation number for Al(NO3)3?
What is the oxidation number of aluminum (Al) in the compound aluminum nitrate, Al(NO3)3? Could you also explain the steps involved in determining it?
1 Answers
An element has an oxidation number, not an entire compound. The sum of the oxidation numbers for a compound is always zero.
In Al(NO3)3, aluminum is +3 and each oxygen is -2. Since you know that the sum of the oxidation numbers is zero, then you can determine the oxidation number of nitrogen.
