Make sure that the joints are sealed and stoppers are properly closed so that gas may not leak. In past we use grease for sealing the joints and but now a days the joints surface are rough so they get sealed itself .

It would be confirm either by silver nitrate test or organic layer test.

Addition of sodium molybdate, will cause the interaction of orthophosphate with molybdate to produce an intense, stable, and water-soluble phosphomolybdate blue complex. The molybdenum blue reaction has been successfully employed to provide a sensitive and quick measuring method to quantify the phosphate content in various water and detergent samples using UV-VIS spectrophotometry.

For qualitative analysis we use ammonium molybdate solution

Mam not bro.😂

Pharmacy wala he kya.

Are bhaiya dynamite bana rahe ho kya jo it’s work likha hai😂😂

No you don't have to boil AgBr . Solubility is checked in ammonia solution that is NH4OH solution at room temperature. AgCl is soluble in dilute ammonia solution and always remember the solution obtained after dissolving in ammonia should be discarded quickly to avoid serious explosion. AgBr is sparingly soluble in dilute ammonia solution and AgI is insoluble in dilute ammonia solution. When ammonia is dissolved in water it forms ammonium hydroxide and both of them exist in equilibrium.

After experiment FeS and H2SO4 is taken out and Apparatus is cleaned .

Thank you mam

Mam in salt analysis what is the molarity of concentrated H2so4

No ,you should not use calcium nitrate as out of Ba,Sr and Ca . Barium Sulphate have least solubility. Ca ion is precipitated as Calcium oxalate in 5 th group analysis just watch the video test for Ca2+ ion.

Thank you so much. Barium sulphate is insoluble in warm dilute hydrochloric acid but moderately soluble in boiling concentrated hydrochloric acid. Hence solubility should be checked by adding dil HCl.
