7.
Which statement best describes Half-equation?
An equation showing either the oxidation or the reduction process with electrons included.
A reaction in which the same element is simultaneously oxidised and reduced.
The point in a titration where the indicator changes colour, ideally matching the equivalence point.
A species that donates electrons and is itself oxidised.
8.
Which statement best describes Disproportionation?
A reaction in which the same element is simultaneously oxidised and reduced.
Loss of electrons, or an increase in oxidation number.
The point in a titration where the indicator changes colour, ideally matching the equivalence point.
A species that accepts electrons and is itself reduced.
9.
Which statement best describes Ionic equation?
The point in a titration where the indicator changes colour, ideally matching the equivalence point.
Gain of electrons, or a decrease in oxidation number.
A reaction in which the same element is simultaneously oxidised and reduced.
An equation showing only the species that take part in a reaction, omitting spectator ions.
10.
Which statement best describes Oxidation number?
A number showing the charge an atom would have if all its bonds were ionic; used to track electron transfer.
An equation showing either the oxidation or the reduction process with electrons included.
A reaction in which the same element is simultaneously oxidised and reduced.
An equation showing only the species that take part in a reaction, omitting spectator ions.

Why is dilute sulfuric acid, not hydrochloric acid, used in manganate(VII) titrations?
HCl is too weak
Cl- would be oxidised by MnO4-
HCl reacts with Fe2+
H2SO4 acts as indicator
