Final answer:
A stable solution will remain unchanged under normal conditions, while an unstable solution may undergo a chemical reaction or exhibit changes in its physical properties. To determine the stability of a solution, you can observe its behavior and compare it to known stable solutions. The stability of a solution can be influenced by factors such as temperature, pressure, and the presence of catalysts.
Step-by-step explanation:
A solution can be determined to be stable or unstable based on its ability to maintain its chemical properties over time. A stable solution will remain unchanged under normal conditions, while an unstable solution may undergo a chemical reaction or exhibit changes in its physical properties. For example, a solution that shows signs of precipitation, gas formation, or color change may be considered unstable.
In order to determine the stability of a solution, you can observe its behavior and compare it to known stable solutions. Additionally, you can conduct experiments to test the solution's reactivity under different conditions. It is important to note that the stability of a solution can be influenced by various factors, such as temperature, pressure, and the presence of catalysts.
