Differentiate between oxide, a peroxide, and a superoxide?
- Chemistry PLZ HELP!!!!! - Laruen, Monday, April 9, 2012 at 3:09pm
In terms of ionic compounds an oxide contain the oxide ion (O2-) Which is a single oxygen atom with a 2- charge.
A peroxide contains the peroxide ion (O22-) which is a particle of two oxygen atoms bonded together and has a 2- charge. Unlike most normal oxides, peroxides tend to be oxidizers or at the very least, unstable.
A superoxide contains the superoxide ion (O2-) which consists of two oxygen atoms bonded together and has a 1- charge. This ion is even more strongly oxidizing than the peroxide ion.
In covalent compounds oxides are substances that contain oxygen in the 2- oxidation state and not bonded ot other oxygen atoms.
Peroxide contain a peroxide group (O2) in which each oxygen atom is bonded to the other oxygen an to another atom, typically carbon or hydrogen. IN this case oxygen is in the 1- oxidation state.

Wow you must be very smart
are you supose to graudated when you 17-18???

Laruen gave you good answers.
The oxidation state of oxygen in oxides is -2. In peroxides it is -1. In super oxides it is -1/2.

Lauren: yes im graduating 2 years early
Bob: that's the one i used!
