The heat energy absorbed or released when a specific amount of solute dissolves in a solvent is the?
The heat energy absorbed or released when a specific amount of solute dissolves in a solvent is called the heat of solution or enthalpy of solution. It represents the overall energy change associated with the dissolution process.
What happens to light that strikes clear plastic?
A common technique in chemistry is spectroscopic analysis. This is where light is passed through a solution to determine its composition. The spectrometer will give a reading of absorbance or percent transmittance. The absorbance tells you how much light is absorbed, while the percent transmittance tells you what percentage of the light passed through and was not absorbed. If when you say clear you mean "colorless," all the light will pass through. The plastic is most likely not entirely colorless so only a small portion of the light will be absorbed, and it will have a high percent transmittance value.
Explain in detain how the spectrophotometer works?
The spectrophotometer is a complex instrument used in measuring the absorbance of biomolecules within the ultraviolet and visible light spectrum, similar to the one found in the laboratory. It is a conglomerate of light sources, wavelength selectors, optical systems, sample chambers, photodetectors, and meters functioning together to perform a specific task - to measure the absorbance of a sample. It works by a light passing through a solution, the higher the M concentration of the solution the more light is absorbed. The percent of transmittance will help analysis the M concentration
What is the unit of absorbance?
Mol-1cm-1
What features of chloroplast help maximize the amount of light that can be absorbed?
it is about the absorbing center. It contains photosynthetic pigments.
What instrument will measure the wavelengths of light absorbed by a solution?
A spectrophotometer is typically used to measure the wavelengths of light absorbed by a solution. This instrument can determine the amount of light of a specific wavelength that is absorbed by the solution, which can provide information about the composition of the solution.
What instramen tmeasures wavelengths of light absorbed by a solution?
A spectrophotometer is used to measure the wavelengths of light absorbed by a solution. It works by passing light through the solution and detecting how much light is absorbed at different wavelengths, allowing researchers to determine the concentration of specific substances in the solution based on the absorption pattern.
What is a photometric titration?
A photometric titration is a method of analyzing a solution by measuring the intensity of light absorbed or emitted by the solution during a titration process. This technique is commonly used to determine the concentration of an analyte in a sample based on the amount of light absorbed or emitted at specific wavelengths.
What is a spectrophotometer and what does it measure?
A spectrophotometer is a scientific instrument that measures the amount of light absorbed or transmitted by a substance at different wavelengths. It is commonly used to determine the concentration of a substance in a solution by measuring how much light is absorbed by the sample.
What happens when a beam of light is passed through a colloidal solution?
When a strong beam of light is passed through a colloidal solution, then scattering of light is absorbed.
How can you measure how much light is absorbed by an opaque object?
You can measure the amount of light absorbed by an opaque object using a spectrophotometer, which measures the amount of light that passes through and is absorbed by the object at different wavelengths. The absorbance value obtained from the spectrophotometer can quantitatively indicate how much light is being absorbed by the object.
Explain what happens when a beam of light passes through a gold solution?
A part of this light is absorbed.
What do you mean by optical density?
Optical density is a measurement of how much light is absorbed or transmitted by a material. It is often used to quantify the amount of a substance in a solution by measuring the absorbance of light passing through it. A higher optical density indicates more absorption of light.
What is the molar absorptivity of CuSO4 and how does it impact the measurement of its concentration in a solution?
The molar absorptivity of CuSO4 is a measure of how well it absorbs light at a specific wavelength. It impacts the measurement of its concentration in a solution by affecting the amount of light absorbed, which is used to determine the concentration through a calibration curve. A higher molar absorptivity means more light is absorbed, leading to a more accurate concentration measurement.
The heat energy absorbed or released when a specific amount of solute dissolves in a solvent is the?
The heat energy absorbed or released when a specific amount of solute dissolves in a solvent is called the heat of solution or enthalpy of solution. It represents the overall energy change associated with the dissolution process.
What happens when light strikes an opaque materials?
The light is absorbed and change to tiny amount of heat
