For organic you can use these tricks If the sample is red colour and has floor cleaner smell its Ar-OH If the sample has vinegar like smell is -COOH if it is red and has bitter almond smell it is -CHO if it is cold (take a drop on your fingertip) its -CO if the sample turns red litmus blue it is -NH (only this turns blue litmus red so do this at first so time will get saved) For salts identify these colours and you will save time google these salts to see exact colour Bright Green - Nickle chloride Peacock green - copper chloride Bluish green - copper acetate Cyan(light blue) - nickle sulphate Red crystal - Cobalt sulphate White flakes - Magnesium chloride White Giltter like- Magnesium sulphate Snow like powder - ammonium carbonate White flakes like sugar - magnesium chloride If you get white colour salt its either magnesium or ammonium and if it has ammonical smell confirm -NH All the best hope this helps 🙏🤞

[@Nachthause]

One thing, my teacher told was that u just have to go and fill the paper with whatever u know. They will give marks. Nobody is going back to see what salt was given on that day. It's just a facade so that students give time to every experiment.

[@megharathore6369]

But in my school they assign salt alternately roll no wise 🥲

And also learn the chemical formula for both Mohr salt and Oxalic acid. 9) Cu is used in identification of which anion? 10) What is the test for CO2? 11) What is the molecular mass of the salt you used in titration?

[@RupaGayathreK]

In Chem the external asked me questions on d and f block, naming reactions and questions from the project.be clear with your words don't blabber. In biology the external asked us to show different stages in mitosis and she was a rude lady she asked questions from human health and disease. And for your benefit study cell cycle cell division from class 11 text book bcause it's based on mitosis in onion root and very basic my external asked me questions from that. And I answered. For physics compare the experiments, activities written in record to the theory you study. For example metre bridge is based on wheat stone bridge so study about it selectively. And study all possible formula and its unit. The lame mistake us students do is we may not know the basic definition like what I'd potential differences and kinetic energy. I was asked basic definition and formula and questions from project. All the best for your practical exam 🎉
