Oxidising and reducing agents Flashcards
1
Q
Name a strong oxidising agent
A
Hydrogen Peroxide
2
Q
What is the strongest oxidising agent in the electrochemical series?
A
Fluorine
3
Q
What is the strongest reducing agent in the electrochemical series?
A
Lithium
4
Q
Reducing agents
A
Substance that donates electrons
5
Q
Oxidising agents
A
Substance that accepts electrons
6
Q
Reduction
A
Is a gain of electrons by a reactant in any reaction
7
Q
Oxidation
A
Is a loss of electrons by a reactant in any reaction
8
Q
Why are the strongest oxidising agents the halogens?
HINT think electronegativity.
A
The Halogens have high electronegativities and gain electrons very easily
9
Q
ClO3− (aq) → Cl2(g)
How would this equation be balanced
A
ClO3− (aq) → Cl2(g)
- Balance chlorines
2ClO3− (aq) → Cl2(g)
- Add waters to balance 0xygens
2ClO3− (aq) → Cl2(g) + 6H2O(l)
- Add H+ to balance hydrogens
2ClO3− (aq) + 12H+(aq) + 10e− → Cl2(g) + 6H2O(l)
