To determine the presence of anion and cation in the given salt
Experiment | Observation | Inference |
---|---|---|
To dry salt, dilute H₂SO₄ is added | No reaction | Dilute H₂SO₄ group is absent |
Salt + Conc H₂SO₄ | Colorless gas with pungent smell evolves | Cl⁻ may be present |
Confirmatory Test | ||
Silver Nitrate Test Salt Solution + Dilute HNO₃ + AgNO₃ solution | White ppt soluble in NH₄OH | Presence of Cl⁻ anion is confirmed |
Experiment | Observation | Inference |
---|---|---|
Salt solution + NaOH solution | Blue precipitate | Cu²⁺ may be present |
Confirmatory Test | ||
Potassium Ferrocyanide Test Salt solution + K₄[Fe(CN)₆] solution | Chocolate brown precipitate | Presence of Cu²⁺ is confirmed |
The given salt contains Cu²⁺ ions as cation and Cl⁻ ions as anion. The salt is Cu²⁺Cl⁻.
