What are two reasons why absorbance measurements are taken at lambda max?
Absorbance measurements are taken at λ max because it represents the wavelength at which a compound absorbs light most strongly, allowing for more accurate and sensitive detection of the compound. Additionally, λ max provides specific information about the electronic structure of the compound, aiding in its identification and characterization.
What is red solution in uv spectroscopy?
In UV spectroscopy, a red solution could indicate the presence of a compound that absorbs light more in the visible range rather than in the UV range. This could be due to the presence of colored impurities in the sample or the compound itself having strong absorbance in the visible region. Further analysis, such as UV-Vis spectroscopy, can provide more information on the specific properties of the red solution.
What the colored chemical compound in plants that that absorbs light?
These compounds are known as photosynthetic pigments.
What is the uv radiation that absorbs oxygen compound?
Ozone (O3) is the ultraviolet radiation that absorbs oxygen molecules in the stratosphere. UV radiation breaks apart oxygen molecules (O2), allowing the loose oxygen atoms to combine with other oxygen molecules to form ozone.
What is in litmus paper that makes it turn red when dipped in a acid?
Litmus paper is a commonly used pH indicator. Litmus is a water-soluable mixture of dyes extracted from lichens. When the paper is dipped into an acidic solution, the paper absorbs a proton from the acidic solution, and it creates a new compound inside the paper that absorbs lower energy light (red light). This makes the paper appear red.
When a solution is red does the solution absorb red light strongly or transmit red light strongly?
When a solution appears red, it absorbs light of complementary colors (green and blue) and transmits or reflects red light. This means that the solution absorbs light in the green and blue portions of the visible spectrum, resulting in the red color that is observed.
What does light absorbs?
Chlorophyll absorbs light most strongly in the blue and red but poorly in the green portions of the electromagnetic spectrum, hence the green color of chlorophyll-containing tissues like plant leaves
What is the extinction coefficient (aka molar absorptivity) for CuSO4 at the wavelength you used?
The extinction coefficient, also known as molar absorptivity, for CuSO4 at the specific wavelength used is a measure of how strongly the compound absorbs light at that wavelength. It is a constant value that helps determine the concentration of the compound in a solution based on its absorbance.
What is the extinction coefficient (aka molar absorptivity) of CuSO4 at the wavelength you used?
The extinction coefficient, also known as molar absorptivity, of CuSO4 at the specific wavelength used is a measure of how strongly the compound absorbs light at that wavelength. It is a constant value that helps determine the concentration of the compound in a solution based on its absorbance.

What is the extinction coefficient of CuSO4 and how does it impact the measurement of its absorbance in a solution?
The extinction coefficient of CuSO4 is a measure of how strongly it absorbs light at a specific wavelength. A higher extinction coefficient means that the substance absorbs more light. This impacts the measurement of its absorbance in a solution because a higher extinction coefficient will result in a higher absorbance reading, indicating a higher concentration of CuSO4 in the solution.
What is peak absorbance?
Peak absorbance refers to the wavelength at which a substance absorbs light most strongly. It is commonly used in spectrophotometry to determine the concentration of a substance in a solution by measuring the absorbance at its peak wavelength.
What is the element that absorbs oxygen?
Pyrogallol,when in alkaline solution, it absorbs oxygen from the air, turning brown from a colourless solution. or simply none
What are colored compound that absorbs light?
the answer is pigments
What are colored chemical compound that absorbs light?
the answer is pigments
Why does the part of leaf inside the bottle containing potassium hydroxide solution not get carbon dioxide?
The leaf inside the bottle containing potassium hydroxide solution does not receive carbon dioxide because the potassium hydroxide absorbs the carbon dioxide present in the air. This creates a carbon dioxide-free environment inside the bottle, preventing the leaf from undergoing photosynthesis.
How does kelp get nutrients?
It absorbs them from the water, where they exist in solution.
