Sir I have a doubt in inorganic chemistry lab ... during the identification of cation in group 2 analysis I passed h2s through my centrifugate I get dark yellow a kind of brown yellow colour. After centrifuge this I get dark colored ppt ..is that indicates cadmium presence? please reply sir.

[@RGChemistry]

If a yellow precipitate is formed in the second group, decide the presence of As3+, Cd2+ and Sn2+ by Confirmative test.

Sir ji isme nitro benzene ka percentage yield kaise calculate krenge

[@RGChemistry]

Sea the video of viva question on organic preparation.

[@thedreamworld6318]

Any link sir ji

[@bollywoodmix7390]

(practical yield/theoretical yield)×100

[@imunknown3735]

During the practical i got only oily products which solidify with ice but whene i filtrate it only oily product reconverts
In this practical our professor told that atleast 1 hours digestion on sand bath

[@RGChemistry]

Oily drop obtained due to unreacted nitro benzene.

[@priyankapanwar1892]

Thanks sir 🙏👍 sir can we prepare m - dinitrobenzene from benzene?

[@RGChemistry]

Yes. In two steps.

[@priyankapanwar1892]

@@RGChemistry can u explain me please 🥺

[@itsme-vv3zb]

Sir when i pour that mixture into ice water i got oily ppt instead of crystal ppt.what is the reason behind this sir?

[@RGChemistry]

Due to unredacted nitro benzene

[@itsme-vv3zb]

@@RGChemistry How can I overcome this?

[@LuckyLucky-pc5uu]

Fuming hno3 means

[@nafisayeasmin4386]

Nitric acid

[@RGChemistry]

Fuming nitric acid acid is Mixture of HNO3 and NO2.

Sir practical book me to air condensor kaha he or vo bhi 1.30 kalak garm karna
Is it right?

[@RGChemistry]

A funnel can be used instead of an air condensor and there is no need to heat for one and a half hours. Only 5-10 minutes of heating is required.

[@RohitJadhav81]

Why to add porcilin pieces ?

[@RGChemistry]

For avoid bumping of the solution.
