What is the molar absorptivity of crystal violet?
The molar absorptivity of crystal violet can be determined using Beer's Law. Beer's Law is A=E*c*l where A is absorbance, E is the molar absorptivity, C is the concentration of the crystal violet, and l is the path length. Path length is how long the light has to travel through the solution. If you can find the absorbance of a certain concentration by using a spectrophotometer, where the path length is 1 cm, then you know all the variables and are able to solve for the molar absorptivity. For example, the measured absorbance of 2.5x10^-5 M CV (crystal violet) is 1.64 with a path length of 1 cm. This means 1.64=E*(2.5x10^-5)*1 E=1.64/(2.5x10^-5) E=65600 Happy Chemistry!
What are the physical properties of shortening?
The process of shortening has the effect of decreasing the physical length or distance of the object or path on which it acts. The process is typically implemented in a progressive, measured manner, but can also be applied suddenly and precipitously, and is then referred to as 'cutting', 'chopping', or 'hacking'.
What sensitivity sandell?
Sandell's sensitivity is defined as the weight of a substance that can be determined in a column of solution having unit cross sections. The weight is expressed in micrograms and the area in cm^2.
What is the function of a salt-bridge in an electrochemical cell to actually migrate ions from one half-cell to another OR the salt-bridge sucks up the ions from a half-cell to make the half-cell neut?
The salt bridge exists to provide the electrical connection between the two reaction vessels while keeping the two reactions separate. The salt bridge provides a path for the charge carriers from one half of the cell to the other half. They migrate along this path when the circuit is closed, driven by the attraction of the anode for electrons or electron-rich species, and the attraction of the cathode for positively charged ions.
Tracking the path and constructing the periodic table?
Tracking path
What is a path length in physics?
the path length of an object in motion in a given time is the length of actual path traversed by the object in the given time.
What are the disadvantages of infrared spectroscopy?
The richness of spectral features enhances the probability of overlapping absorption bands.The narrow path-length cells required for many analysis are inconvenient to use and may lead to significant uncertainties.
What is the average path length of a tornado?
The average tornado has a path length of 2 to 3 miles.
The quantity that describes the length of an objects path only?
Distance is the quantity that describes length of an object's path only no matter what path is covered.
What is the length of a path between two points?
The Length of a path between two points is known as distance.
What is the symbol of path length?
j
Is a tornado's width measured at the top or bottom?
A tornado's width is measured at bottom, usually by the width of the damage path.
What is the length of actual path covered?
Distance :))
What is path difference measured in?
There's not much to go on, so I have to guess. The phrase "path difference" is one that often pops up in radio or light propagation, where it's measured in wavelengths (at the operating frequency).
In a plot of absorbance vs concentration what does the slope represent?
The slope of absorbance vs concentration reptresents the value of εb, where ε is the absorbtivity with units of (L/mol cm) and b is path length measured in cm.
Why would a measured value of Zs for a circuit be lower than the calculated value?
Possible parallel earth path/s when measured!
Can you make infrared rays follow a particular white path?
You cannot. Infra red is electromagnetic and follows the rules of physics.
