Brown ring test is salt analysis for the confirmation of nitrate ion. Magnetic moment of the complex formed is x BM comes out to be up to two decimal deduce that to single digit. For example if x = 2.73 add 2+7+3=12 and than again 1+ 2 = 3. So, answer will be 3.

The ‘brown ring test’ is also known as test for------------A. Halide ionB. Sulphate ionC. Nitrate ionD. Ammonium ion

What can be inferred from the magnetic moment values of the following complex species?Example Magnetic Moment (BM)K4[Mn(CN)6] 2.2[Fe(H2O)6]2+ 5.3K2[MnCl4] 5.9

In the brown ring test, the dark brown ring is observed-----------------A. above the two layers of the liquidsB. at the junction of the two liquid’s layersC. at the bottom of the two liquid’s layersD. beside the meeting point of the two liquid’s layers

. What can be inferred from the magnetic moment values of the following complex species?

The table shows the properties of four elements. Which test would MOST help a chemist identify which sample is nitrogen?ATry to burn each sampleBObserve the color of each sampleCObserve the state of matter of each sampleDTest each sample with a magnet
