@Supreeta_Sen But this is not given in both Grp 1 and Grp 2, where is it given then?
Even this isn't given anywhere in notes.
In my book that HgCrO4 is in grp 1 bro
Yeah I’ll upload in some time bro.
All chromates except this one and silver are yellow. I'm not sure about out of syllabus cations, but for syllabus one this works.
If you have any such thumb rules please post, will help a lot.
