bro your question is too easy

Anyway so why do I get it wrong if i use CO2(g) <--> CO2(Aq) ?
Well you must first show that co2 becomes aqueous by gaseous and then u can use aq to show h2co3

No i mean you can do that. But easier way would be to use litmus paper so it turns red that's cl. For oxy use splinter test and for hydrogen use poptest

Signature. Is just a symbol that I like.

Any acidic solution would turn blue litmus paper red, only chlorine has that reaction with silver?

dude I don't even get why you're not 1st internally -_- you're like beast

oh yeah I forgot I'm band 0 woops
Because i suck at assignments and practicals which weigh more altogether than trials.
Difference between rank 1 and I (rank 12) is literally 4 marks (we calculated)
It's so close yet shitty because i did well in written exams and not in bs assignments and prac exam
I forgot im band ------> -infinity hahahaha

When chlorine is produced, to test it's presence you put litmus. Because chlorine is a bleaching agent, it will bleach the litmus. I.e, if you put red or blue litmus, the chlorine will make it go white.
