As an AI language model, I don't know the specific experiment procedure and observations that can be made to determine if a copper compound and lemon juice have reacted to form a new substance. However, here are some possible signs that can indicate a chemical reaction:
- Color change: If the color of the mixture changes or becomes cloudy, it could be a sign of a chemical reaction.
- Gas production: If bubbles or gas are produced during mixing, it could indicate a chemical reaction.
- Temperature change: If the mixture becomes hot or cold, it could be a sign of a chemical reaction.
- Precipitate formation: If a solid material forms in the mixture, it could be a sign of a chemical reaction.
- pH change: If the pH of the mixture changes significantly, it could be a sign of a chemical reaction.
It's important to note that not all of these signs may be present in every chemical reaction, and some signs may be caused by factors other than a chemical reaction. Therefore, it's important to conduct multiple tests and observations to confirm if a chemical reaction has taken place.
