How can you figure out Absorbance without percent transmittance?

A=logIo/I


Does a higher percent of transmittance mean there is more aerobic respiration?

A higher percent of transmittance in a solution typically indicates that more light is passing through, suggesting lower absorbance by the substances present. In the context of aerobic respiration, if transmittance is measured for a product like carbon dioxide or a byproduct of respiration, a higher percent could imply more aerobic respiration is occurring. However, transmittance alone doesn't directly measure respiration; it must be considered alongside other factors like the specific substances being analyzed.


What is the relationship between absorbance and transmittance?

Absorbance = -log (percent transmittance/100)


Light transmittance can be more then 100 percent?

logically no because if it is a yes, then the light reaching the detector is greater than the light which was produced by the machine in the first place. But you may get transmittance greater than 100 because some parameters of your experiment may not be right.


What reasons can you give for the difference in the percentage of transmittance between the live chlorplats that were incubated in the light and those that were kept in the dark?

The percent transmittance grew to steadily higher numbers as the experiment progressed because the light reaction was able to occur. However, the dark cuvettes had stable levels of transmittance because light is necessary to excite electrons, which, in turn, reduces the DPIP.


Why do ir spectra seldom show regions at which the transmittance is 100 percent?

IR spectra seldom show regions at 100% transmittance because most molecules absorb some infrared radiation due to their unique bond vibrations. Even if there are no absorptions in a particular region, factors like impurities, instrument noise, or scattering can lead to a lack of complete transmittance.


What happens to light that strikes clear plastic?

Light can pass through clear plastic, with some of it being absorbed and some being transmitted. The amount of light that is transmitted or absorbed depends on the thickness and composition of the plastic.


What is the unit of transmittance?

There is none.


What is the advantage of reading the absorbance rather than the percent transmittance on the spectrophotometer?

Reading absorbance values is advantageous because it provides a linear relationship with concentration, making it easier to quantify the amount of substance present in a sample. Percent transmittance, on the other hand, is a non-linear measurement that can be affected by factors like stray light, making it less accurate for quantitative analysis.


Why do chemists prefer to read the absorbance rather than the percent transmittance of lght when analyzing a sample having a visible color?

Chemists prefer to read the absorbance rather than the percent transmittance of light when analyzing a sample with a visible color because absorbance is directly proportional to concentration according to the Beer-Lambert Law. This allows for more accurate quantification of the sample's components. In contrast, percent transmittance may not provide a linear response and can be influenced by factors beyond just concentration, such as the color of the sample itself.


The lower transmittance of film indicates higher absorption or reflectance?

The lower transmittance of film would indicate a higher Optical Density (OD), or absorption, because as concentration increases, % transmittance will decrease. This is because of Beer's Law (A = 2.00 -[log (%T)]). As you can see from the equation, transmittance is directly proportional to the outcome of absorption. High %T = Lower Absorption.Low %T = Higher Absorption.
