Q1 · Salt Analysis (Practical) · EASY
A salt solution gives a white precipitate with dilute HCl which is insoluble in hot water. The cation present in the salt is:
Q2 · Salt Analysis (Practical) · EASY
In the systematic qualitative analysis of cations, Group II is precipitated using H₂S in the presence of dilute HCl. Which of the following cations belongs to Group II?
Q3 · Salt Analysis (Practical) · MEDIUM
A solution of a salt gives a brown ring test positive. When treated with BaCl₂ solution, a white precipitate is formed which is insoluble in dilute HCl. The anion present in the salt is:
Q4 · Salt Analysis (Practical) · MEDIUM
A white salt is soluble in water. Its aqueous solution gives a white precipitate with NaOH which is insoluble in excess of NaOH but soluble in excess of NH₄OH. The cation present is:
Q5 · Salt Analysis (Practical) · HARD
During the analysis of a mixture of Group III cations (Al³⁺, Fe³⁺, Cr³⁺), the precipitate obtained after adding NH₄OH and NH₄Cl is boiled with sodium peroxide (Na₂O₂) and the solution is acidified. A yellow solution is obtained which on treatment with lead acetate gives a yellow precipitate. Which cation is confirmed by this test?
