Solution

When chlorine is added to cola, several observable chemical changes could occur. Here are the key points regarding each possible observation:

  1. Formation of a Gas: The reaction between chlorine and certain components in cola (such as sugars or other organic compounds) may lead to the release of gases such as carbon dioxide. This is a common observation when acids or bases react with carbonate compounds, which might be present in cola.

  2. Change in Colour: Chlorine is a strong oxidizing agent and may react with colorants in cola, potentially leading to a color change. For example, the dark color of cola could lighten as the chlorine reacts with and breaks down some of the colorants.

  3. Formation of a New Solid: Depending on the concentration of chlorine and the specific substances present in cola, a precipitate might form as a result of reaction products. This could include solid chlorinated organic compounds.

Given these points, it’s plausible that all of these chemical changes could occur simultaneously when chlorine is added to cola. If you are unsure which specific observation to focus on, it's important to consider the context of the experiment or reaction being investigated.

Overall, adding chlorine can lead to significant chemical changes, and careful observation would be required to identify each one accurately.
