An optical rotation study gives result of +140 degrees. Suggest a dilution experiment to test whether the results is indeed +140 degrees, not-200 degrees.
THANK YOU!
are u sure its not -220? i think we're looking for the same answer lol
Oh it is, but same idea.
To verify the result obtained from the optical rotation study, you can perform a dilution experiment to test if the observed optical rotation value remains consistent. Here's how you can go about it:
1. Start by preparing a series of dilutions using the sample that yielded the original +140 degrees result. For example, you can prepare dilutions of 1:2, 1:4, 1:8, and so on. This can be done by taking a specific volume of the sample and diluting it with an appropriate solvent (such as water or ethanol) to achieve the desired dilution factor.
2. Once the dilutions are prepared, measure the optical rotation of each dilution using the same experimental setup and conditions as the original study. Make sure to use the same wavelength and temperature to maintain consistency.
3. Compare the observed optical rotation values of the dilutions with the original +140 degrees result. If the dilutions yield optical rotation values that are in agreement with the original value, it supports the accuracy of the +140 degrees result. However, if the dilutions give significantly different optical rotation values, it indicates a potential error or inconsistency in the initial measurement.
By performing this dilution experiment, you can determine whether the observed optical rotation value is consistent across different dilutions, thus establishing the reliability of the +140 degrees result.
