Short explanation

For this page, chlorine gas is revised through the specific task: Describe the test for chlorine using damp litmus paper. The approved objective is: Describe the test for chlorine using damp litmus paper. The key evidence is damp litmus paper, and the result to look for is bleaches. This makes it different from nearby objectives because the answer must stay anchored to Describe the test for chlorine using damp litmus paper, not another Chemical analysis test. Useful curriculum keywords include chlorine and damp litmus paper. Keep the method, observation, and conclusion separate so the answer does not confuse gas tests, flame tests, cation tests, anion tests, chromatography, pure substances, or formulations. A strong exam response states the test or measurement, describes what is seen, and then links that evidence directly to Test for chlorine.
