Answer 2

[AI-generated answer — Explain Bot]

Yes, the correct answer is A. The chemist's observation that a solution turns blue when a chemical reaction takes place is a qualitative observation. A qualitative observation is related to the qualities or properties of something, and it doesn't involve numerical or measurable information. In this case, the chemist is simply noting the color change, which is a qualitative characteristic.

Yes, the correct answer is A. The chemist's observation that the solution turns blue is a qualitative observation. Qualitative observations describe properties or characteristics without measuring or quantifying them. In this case, the chemist is simply noting the change in color of the solution, without giving any specific measurements or quantities.
