Question

The absorbance of a dilute aspirin solution (diluted with fecl3) generates an error -- too concentrated. after showing your ta that you cannot determine the absorbance of the solution, the ta tells you to make a new dilute aspirin solution. when making a new solution, should it be more concentrated or less concentrated?

Answer 1

When making a new solution, the solution SHOULD BE LESS CONCENTRATED.
Since the concentration of the first solution is said to be too high, the concentration of the new solution that will be produced should be less than that of the first solution. This is necessary in order to keep the concentration of the solution within the range of the spectrophotometer capacity.
