LT#1: Identifying Redox Flashcards
In organic chemistry Oxidation is defined as…
Increasing C-O bonds
When dealing with ionic or charged compounds, Oxidation is defined as…
Losing electrons
When dealing with molecular compounds, Oxidation is defined as…
An increase in oxidation number
In organic chemistry Reduction is defined as…
Decrease in C-O bonds
When dealing with ionic or charged compounds, Reduction is defined as…
Gaining Electrons
When dealing with molecular compounds, Oxidation is defined as…
A decrease in oxidation number
Why are the names of Oxidation and Reduction reactions combined into Redox?
Because both reactions always happen simultaneously
Define Oxidizing Agent. How do you recognize them?
The chemical that causes the other reactant to oxidize.
Either removes electrons from the oxidized chemical or causes it’s oxidation number to go up, causing the oxidizing agent to become reduced.
Define Reducing Agent. How do you recognize them?
The chemical that causes the other reactant to become reduced.
Either supplies electrons to the reduced chemical or causes it’s oxidation number to go down, causing the reducing agent to become oxidized.
What are the steps involved in writing a net ionic equation?
Break aq chemicals apart into their separate ions, then remove any spectators
Define the term Half Reaction
Balanced equations showing an oxidation or reduction separately, including the electrons lost or gained.
What are the steps involved in writing a half reaction?
Write the correct reactant and product, then add coefficients to balance the atoms as usual.
Add electrons so that the total charge on the left side of the equation equals the right side.
A pure element has an oxidation number of?
0
The oxidation number of an ion equals?
The charge of the ion.
Hydrogen in a compound usually has an oxidation number of?
+1
