How did people find the chem paper? Honestly, I found it good. Then when I checked multiple choice, I realised I made various silly mistakes. I think I'm going to lose about 9 marks in the core, and about 4 marks in the option. By the way, how do you identify the products of electrolysis of NaCl? (Industrial) I wrote about indicators for OH- ions, and I think the same for hydrogen. Don't know what I wrote for chlorine though.
