something bout absorbance(spectrophotometer)
« on: August 14, 2005, 02:20:20 AM »
i have a question here regarding this:

why is it sometimes that a higher wavelength o sometimes a lower wavelength was used in spectrophotometer to test the absorbance for a solution? there shoud be 2 reasons from the questions asked...i'm not sure what?...thanks

Different solutions will absorb at different wavelengths.

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

Even if one sample, it can also have more than one aborption at particular wavelengths.

yup true @ wicky... d trick is to get the wavelength at where it has the highest absorbance? but why?
