WebExplain. The calculated molar volume of CO2 will be too low because the crack of the rubber stopper allows CO2 to leak out from the generator. With this, the volume of CO2 will be very low and the molar volume will be lower as well. An air bubble accidentally enters the CO2 collection graduated cylinder after the completion of the reaction. WebThe absorbance of bromophenol blue solutions in tube 1-6 from Part 2 is measured at Amax of methyl orange (460nm), while the absorbance of different concentration of methyl orange solutions were also measured at Amax of methyl orange (460nm) and Amax of bromophenol blue (590nm).
WebJan 30, 2024 · If it is in a reasonably concentrated solution, it will have a very high absorbance because there are lots of molecules to interact with the light. However, in an incredibly dilute solution, it may be very difficult to see that it is colored at all. The absorbance is going to be very low. WebHere, maximum absorbance is at 630 nm, in the orange range of the visible spectrum, and the compound appears blue.
