Question

Suppose the percent transmittance of a solution of Procion Red is measured. If adding bentonite clay sequesters dye molecules from solution, removing the clay would cause the measured percent transmittance to O increase. O decrease O stay the same O This cannot be determined. Consider what would happen if absorbance were monitored rather than percent transmittance in the previously described scenario. Removing the clay from solution would cause the measured absorbance to increase decrease stay the same. O This cannot be determined.

Explanation / Answer

1) Assume the percent transmittance of a solution of Procion Red is measured. On the off chance that including bentonite clay sequesters dye molecules from solution, evacuating the clay would make the deliberate percent transmittance to increase.

Option a) increase

2) Consider what might happen if absorbance were observed instead of percent transmittance in the previuosly composed situation. Expelling the clay from solution would make the deliberate absorbance to decrease.

Option b) decrease
