Step-by-step explanation:
A qualitative observation is a subjective observation, we collect data through our senses.
"The temperature is 95.2 °C" we may have measured the temperature with a thermometer.
"The volume is 5.6 L" we may have used a graduated cylinder to measure to the volume.
But if the color of the solution is green or if a liquid is odorless is something subjective. We don't see in the same way and there are lots of different greens, and we smell different. Some people are more sensible to some aromas than others.
Answer: The solution is green. The liquid is odorless.
