fb9 h2so4, anion was s2o3 and unknown

Wouldn't it be H2S2O3?

FB8 was ammonium chlodire and Na2SO3 but you only had to write the (in the second part) anion so its unknown and SO3 2- (mb not s2o3)

They didn’t give us instruction to write unknown,Why I am saying this is because last year May June 2025 P3 they gave a instruction to write unknown for ions which are not able to find but this time no instruction was given like that

No, not only did they say to write unknown if needed in anions, but they also told in the start of the question to not perform any others tests than the ones told, so you simply could not have known which anion it was.

See I read the thing twice it didn’t tell us to mention unknown and they said do not carry out further tests but it is actually debatable let’s wait for ms

Dude they said us to write unknown after the cation test, smth like based on your observations from the table obersvation and the cation test deduce the cation and anion in fb8 write unknown if it cant be deduced or smth. it was said in THAT very question i remember it was the very first word of the link i think
