Brown ring test for nitrate ion in laboratory CBSE/NEET/JEE prep 2025. by Seema Makhijani.

One of the most difficult ones. Even teachers sometimes fail to perform perfectly.

During my practical it took most of my peers atleast 2-3 attempts to perform this successfully, however I am glad it I saw this video just 1 day prior to my practical and was able to perform it successfully at the very first attempt only. Really helpful. Thanks.

[@Arya-cs7kj]

Damn! This is like master class on the brown ring test. 😅 I was specially surprised at the end when she told that the ring is formed below the test tube b'coz of the less acid content. Excellently articulated!

[@Bhakta-zy1be]

While adding concentrated acids always a holder should be used. In practicals this carries marks. 🙂

[@_priya336]

They should also use gloves for the protection of their hands

[@juzeralirangwala3539]

Good explanation.....but small piece of advice.....never use Tap water to make O.S especially in case of nitrates because all of nitrates are highly water soluble so it is quite obvious to have some nitrate impurity in tap water.....instead prefer distill water for preparing O.S because they provide more reliable results......

[@jericho7251]

What is os?

[@juzeralirangwala3539]

@@jericho7251 Original Solution in terms of qualitative analysis O.S means solution of original salt or mixture in aqueos or acidic solvents........ while detecting metal ions which are insoluble in water O.S is made in dilute acids for example salts of carbonates are usually dissolved in dil HCL instead of water
