Testing for Ions quiz Loading... 1. When testing for halide ions, after silver nitrate is added to a sample a white precipitate is formed. Give the formula of the anion present in the sample.CO₃²⁻SO₄²⁻I⁻Cl⁻Question 1 of 10 Loading... 2. In a flame test, a red colour is seen. Give the formula of the cation which is present.Cu²⁺K⁺Na⁺Li⁺Question 2 of 10 Loading... 3. How would you test for the ammonium ion (NH₄⁺)?Add sodium hydroxide. If ammonium ions were present, ammonia gas will form which will bleach damp red litmus paperGently heat it. If ammonium ions were present, ammonia gas will be given off which will bleach damp red litmus paperGently heat it. If ammonium ions were present, ammonia gas will be given off which will turn damp red litmus paper blueAdd sodium hydroxide. If ammonium ions were present, ammonia gas will form which will turn damp red litmus paper blueQuestion 3 of 10 Loading... 4. In a flame test, a lilac colour is seen.
