Kinetics, Equilibria and Redox Reactions Flashcards
What is oxidation?
Oxidation is the loss of electrons
What is reduction?
Reduction is the gain of electrons
What is a redox reaction?
A redox reaction is when reduction and oxidation occur simultaneously
What is an oxidizing agent?
An oxidizing agent accepts electrons and gets reduced
What is a reducing agent?
A reducing agent donates electrons and gets oxidized
What oxidation states do elemental molecules and elemental atoms have?
0
What is the oxidation state of a simple monatomic atom?
It is usually the same as its charge
What is the oxidation state in an ion?
The overall oxidation state is just the ion charge
What is the sum of oxidation states for a neutral compound?
0
When is oxygen not -2 oxidation state?
when it is in a peroxide in which it is -1
when it is in a fluoride in which it is +2 or +1
What do Roman numerals in a compound mean?
It shows the oxidation number
What do ionic half equations show?
They either show reduction or oxidation
How do you combine ionic half equations?
You can combine them to make full equations of redox reactions. you do this by balancing out the electrons on each equation.
