\(BaSO_3 \stackrel{dil.HCL}{→} SO_2 ↑\)
X (gas)
Gas is released with smell of burning sulphur.
The monomer (X) involved in the synthesis of Nylon 6,6 gives positive carbylamine test. If 10 moles of X are analyzed using Dumas method, the amount (in grams) of nitrogen gas evolved is ____. Use: Atomic mass of N (in amu) = 14
The correct match of the group reagents in List-I for precipitating the metal ion given in List-II from solutions is:
List-I | List-II |
---|---|
(P) Passing H2S in the presence of NH4OH | (1) Cu2+ |
(Q) (NH4)2CO3 in the presence of NH4OH | (2) Al3+ |
(R) NH4OH in the presence of NH4Cl | (3) Mn2+ |
(S) Passing H2S in the presence of dilute HCl | (4) Ba2+ (5) Mg2+ |

Qualitative Analysis involves the systematic identification of ions present in a mixture. It focuses on the properties and reactions of ions, particularly cations. The process begins with the systematic analysis of cations, where precipitation reactions are utilized to sequentially remove cations from a mixture. Students learn to recognize characteristic reactions and observe precipitates, helping identify specific ions.
