WebThe 2nd group of anions consist of Cl −, Br −, I −, NO − 3 and C 2 O 2− 4. The group reagent for Group 2 anion is concentrated sulfuric acid (H 2 SO 4 ). After addition of the acid, chlorides, bromides and iodides will form precipitates with silver nitrate. The precipitates are white, pale yellow, and yellow, respectively. WebGroup reagent : H2S in presence of NH4OH. Principle: In alkaline medium, H2S is highly ionized and so concentration of S2- is high. When H2S is passed, sulphides of Zn2+, Ni2+, Co2+ and Mn2+ are precipitated. Why can H₂s in presence of dilute HCl precipitate out only second group radicals but not fourth group radicals?
