Procedure: Add 5 drops of silver salt (Ag+) solution to a test tube and then add 2 drops of 2M HCl. Observe formation of AgCl white precipitate. Add water ... |
AgCl is white, AgBr is cream colored, and AgI is yellow. The color may be a clue to the identity of the anion, but is not always reliable since the colors ... |
For the systematic identification of the anions present in any mixture, the anions are divided into following three classes: 4.2.1 Anions of Class I. The ... |
the identity of an anion is usually twofold: 1) an initial reaction to predict the possibility of a particular ion and 2) a confirmatory test specific to the ... |
(i) Preliminary examination of solid salt and its solution. (ii) Determination of anions by reactions carried out in solution (wet tests) and confirmatory tests ... |
After getting a positive preliminary test for an anion or anion, a confirmatory test must be conducted to confirm the presence of that anion in the salt. |
Positive identification of the anion can be achieved by reacting the precipitate with the oxidizing agent, Cl2 (as chlorine water), and. CH2Cl2, followed by ... |
Anion in a mixture may precipitate in the presence of a specific cation, while other anions will not. By this method, we will be able to identify the unknown ... |
