i was shocked see the. paper....
no question related to mechanism ..that would be free marks.....no definitions ,.....no ionization energy trend etc ( that we normally get)....we got questions from GCSEs....

That's exactly what i did, though i assume the answers may fall within a certain range as i used 2.7 and 5.75...

This is the answer:
Electrolysis of copper chromate. A video showing the electrolysis of copper chromate solution. The initial solution is green. The yellow chromate ions (negative) and blue copper ions (positive) move in opposite directions, forming two coloured bands.

so it was B, yellow.
