IGCSE CHEM PRACTICAL 52

[don8ld994]

Any tips on this? I'm having a hard time describing the colour, sometimes the colour is not a solid colour like orange or black. How do I interpret it successfully?
Another thing if the Mark Scheme said getting paler, but I wrote getting lighter, is it correct? Does the examiner mark to exact or if something is similar it is mark as a right answer.

Thanks !

Ummm... Someone else answer that??? And As far as the last part is concerned I guess he does not mark to the exact I hope its that so...
