Equals the charge of that ion
What does the sum of the oxidation number on a polyatomic ion must equal to?
|
Any chemical process in which elements undergo changes in oxidation number
What is a redox reaction?
|
Oxygen has an oxidation number of -2 unless it is combined with F, in which the oxidation number is +1. When oxygen is in a peroxide then the oxidation number is -1.
What are the rules of oxidation numbers in oxygen?
|
It equals to the charge of the ion.
What equals to the sum of the oxidation number of all polyatomic ions?
|
Process in which an atom gains electrons
What is the definition of reduction?
|
|
It adds up to zero
In neutral molecules, what does the sum of the oxidation numbers adds up to?
|
2(OH-)
What do you add when you want to balance oxygen in a base redox problem?
|
-1

|
Equals -1
Within compounds, Fluorine always equals what?
|
Element that loses one or more electrons and its oxidation number increases
What is the oxidized element?
|
|
Equals the charge of that ion
What does the oxidation number of a monatomic ion equal to?
|
Acids and Base reactions
What are the two types of redox reactions?
|
Hydrogen’s oxidation in most compounds is +1. Unless it is combined with a metal, then it is -1
What are the rule of oxidation in hydrogen?
|
Equal -2
Except with the present of Fluorine within compounds and in oxygen-oxygen bonds, Oxygen always equals what?
|
Element that gains one or more electrons and its oxidation number decreases.
What is the reduced element?

The oxidizing agent causes the oxidation of another substance by accepting electrons from that substance.
What is oxidizing agent?
|
|
Process in which an atom loses electrons.
