Final answer:
To determine which flask holds which sucrose solution, you can use a method called titration. This involves adding a known solution that does not contain sucrose to each flask and noting when the indicator solution changes color. By comparing the volumes of the known solution required for each flask, you can determine the relative concentrations of the sucrose solutions.
Step-by-step explanation:
In order to determine which flask holds which solution, we can use a method called titration. Here's how it works:
- Take a small sample from each flask and add a few drops of an indicator solution that changes color in the presence of sucrose.
- Start with the lowest concentration flask and slowly add a known concentration of a different solution (e.g., water) that does not contain sucrose.
- Continue to add the known solution until the indicator solution changes color, indicating that all the sucrose in the flask has reacted with the added solution.
- Repeat this process for each flask, starting with the lowest concentration and working your way up.
- By comparing the volume of known solution required to change the color of the indicator in each flask, you can determine the relative concentrations of the sucrose solutions.
