Anions go to the .
Cations go to the .
Electolysis is the breaking down of a substance using .
This is an example of a half equation at the anode: 2Cl- (l) Cl2 (aq) + 2e-
What is produced at the cathode if the element is more reactive than hydrogen
The element itself
Hydrogen gas
What is the most common oxidation state of oxygen?
+1
-1
-2
+2
The oxidation state of a monatomic ion is 0.
In a redox reaction
Loss of electrons is called oxidation
Loss of electrons is called reduction
Reducing agents are oxidised and oxidising agents are reduced.
Volatility of halogens ❌ down the group.
Halogens are more soluble in organic solvents than in water because
They are polar
They are non-polar
They don't contain covelant bonds
Chlorine is a ❌ at RTP.
HF and HCl are not stable when heated.
An equilibrium constant that is less than 1 lies to the ❌.
Increasing the pressure in an equilibrium reaction shifts the posisition of equilibrium to the side with gas molecule to the pressure.
