Transcribed Image Text:**Question:**
You have two solutions of the same compound that are blue. One is very pale and the other is very intense. Absorbance of each solution was measured with a spectrophotometer at the same wavelength at which the solution absorbs.
a) Which solution has the higher absorbance?
b) Which is the more concentrated solution?
---
**Explanation:**
This problem involves the concept of absorbance and concentration of solutions. In general, the intensity of color in a solution can provide a visual cue for its concentration; more intense colors typically indicate higher concentrations of the solute. Absorbance, measured by a spectrophotometer, correlates with the concentration according to Beer-Lambert Law, which states that absorbance is directly proportional to concentration. Therefore, solutions with higher absorbance are typically more concentrated.
