Sulfuric acid is added slowly along the side of the test tube so that the sulfuric acid forms a layer just below the aqueous solution of nitrate which is already present in the test tube ,and the purple ring will be produced at the junction of the aqueous phase
Thank you for this clear presentation
Thank you for this! Truly a great video to visualize the experiment.
thank you sir. the concept is crystal clear
concept too clear,thanks sir
Why we should add HCL slowly?
To make layers
@@zhanessj8361 thank you for your answer 🙏
Its H2S04
Because h2so4 is a strong acid isiliye use use bahut dhyan sa use Krna chahia ussa jlna ka khatra hota h
so that it will get time to react and will form a layer.
We tried the same procedure but it turns out there was no violet ring in the test tube. What does that mean?
hello, i would like to ask if the results would be the same if we added more than 3 drops of molisch's regeant as well as the sulfuric acid?
as long as the analyte contains the target substance, it will show result
@@TheSingtangpaScienceGuy thank you so much!
Fructose is a hexose monosaccharide
It's good and concepts clear
Aj Mera lab ma partical h as Ka nice videos ❤❤
why test tube is slanted when adding H2S04
