1
Q
What is a disproportionation reaction?
A
The same species being oxidised and reduced in the same reaction simultaneously
2
Q
What is a redox reaction?
A
OILRIG
Ox is loss of electrons
Reduce is gain of electrons
3
Q
What is ClO- called?
A
Chlorate (I) ion
4
Q
How to determine oxidising power of an agent?
A
Higher oxidising number change in the other reactant
eg FeCl3 makes Fe 3+, FeI2 makes Fe 2+. Higher ox num in Fe 3+ so Cl is a stronger oxidising agent.
5
Q
How is BeCl2 bonded?
A
It is simple covalent bonding
Since Be is very polarising due to small ionic radius
6
Q
How does BaO + H2SO4 react?
A
Very briefly
Stops once its starts
Since BaSO4 is very insoluble
7
Q
How does BaO + HNO3 react?
A
To completion
Since Ba(NO3)2 is very soluble
