What else can I help you with?
If a solution is diluted will the absorbance decrease or increase?
If a solution is diluted, the absorbance will generally decrease. This is because the concentration of the absorbing species is lower in the diluted solution, resulting in fewer molecules to interact with the incident light and therefore lower absorbance.
Why absorbance is decreased after maximum wavelength achieved?
After reaching maximum absorbance at a certain wavelength, further increase in wavelength leads to decreased absorbance because the molecules are not absorbing light at those wavelengths as efficiently. This decrease may be attributed to a shift in the electronic energy levels of the molecules, causing them to absorb less light as the wavelength increases beyond the maximum.
What is the specific absorbance of aspirin?
If you have a spectrofotometer ( the thing to mesure the absorbance) then play with the setting and use a maximum. this will lay close to your specific absorbance or take the pharmacopea or a MERCK index
What is baseline in uv?
In UV spectroscopy, the baseline refers to the horizontal line at zero absorbance on the absorbance axis. It represents the reference point for measuring the absorbance of the sample. The baseline should be stable and noise-free to ensure accurate measurement of the absorbance of the sample.
Removing heat from the air will the air temperature?
Removing heat from the air will decrease the air temperature. Heat is what gives particles in the air energy to move and the removal of heat will cause the particles to slow down, resulting in a decrease in temperature.

If a solution is diluted, the absorbance will generally decrease. This is because the concentration of the absorbing species is lower in the diluted solution, resulting in fewer molecules to interact with the incident light and therefore lower absorbance.
Is wavelength or absorbance the dependent variable?
"absorbance"Since in the experiment, you probably choose the wavelength, then measure the absorbance (absorption?, the absorbance is the dependent variable.
What is the purpose of the blank?
Blank Sample in Spectrophotometry is used to measure the absorbance of light without sample. It is subtracted from the total absorbance for measurement of Absorbance from a sample's absorbance.
How would you modify your procedure if your experimental absorbance is greater than 1?
If the experimental absorbance is greater than 1, you can dilute the sample or use a shorter path length cuvette to decrease the absorbance value within the instrument's linear range. Alternatively, you can try adjusting the wavelength of the spectrophotometer to a different range where the absorbance falls within the linear range. Always ensure that the instrument is set to the appropriate range and that the measurements are made within the linear range to obtain accurate results.
What is difference between specific absorbance and absorbance interms of spectroscopy?
specific absorbance- it is absorbance in a solution containing one gm of substance in 100 ml solvent in 1cm shell. so it is having a difference with absorbance which is negative logarithm of incident light to the transmitted light. divya.chakraborty@gmail.com

Is absorbance considered a discrete or continuous variable?
Absorbance is considered a continuous variable.
What is the different between primary absorbance and secondary absorbance in fluorescence?
in primary light absorbed by outer molecule while in secondary re-absorbance occurs

What is the abbreviation for Absorbance?
A
