Gallium is not a transition metal that has multiple oxidation levels. The other two elements, H and S are non-metals and do not contain roman numerals.
Answer:
The difference between the endpoint and the equivalence point is that the endpoint is the point where your indicator will show a change in colour, your equivalence point however is the point when the analyte has completely reacted with the titrant. So the endpoint is when the indicator may change colours, the equivalence point is when the analyte and titrant are stoichiometrically equal
