Why is o-xylene used as an internal standard in this experiment?
Meen1503
Oxylene is used as an internal standard in experiments because it absorbs a wide area. It also absorbs other compounds easily.

What is the primary standard used in this experiment .define a primary standard?
It is primary standard is a substance that has a known high digree of purity ,reatively large molar mass ,is nonhygroscopic and reacts in a predic table way.
Who used the gold foil experiment?
Ernest Rutherford used the gold foil experiment in 1908 .
What is the dissolving medium used in the experiment?
In order to know what the dissolving medium used in an experiment one would need to know more information in regard to the experiment.
What would be the results for a standard titration experiment?
A titration experiment or procedure uses a reactant to find the quantity of a particular substance dissolved in a solution. The reactant is added slowly and a color change occurs and disappears when stirred. The end point is found when the slightest hint of color remains. The amount of reactant used is measured and used to calculate the concentration of the substance being tested for.
Why is phenolphthalein is used in titration experiment?
it is used as an acid-base indicator
Standard used for comparison in an experiment?
the control
What in an experiment is the standard used to compare with the outcome?
The control is the standard used to compare with the experimental results.
What is the standard used to compare in an experiment?
That would be the control....i think....:)
Why internal standard you used in hplc method?
Internal standard can be used for calibration by plotting the ratio of the analyte signal to the internal standard signal as a function of the analyte concentration of the standards. This is done to correct for the loss of analyte during sample preparation or sample inlet.
What is the difference between standard error and standard deviation?
Standard error is the difference between a researcher's actual findings and their expected findings. Standard error measures the accuracy of one's predictions. Standard deviation is the difference between the results of one's experiment as compared with other results within that experiment. Standard deviation is used to measure the consistency of one's experiment.
The standard for comparison in a experiment?
The standard for comparison in a experiment is known as a control variable. This is useful to any experiment and serves as a reference point used to draw conclusions.
What are factors that are held constant throughout an experiment called?
Constants are factors in an experiment that stay the same. This should not be confused with controls -- which is a standard used for comparison
A part of an experiment to which you can compare the results of other tests?
Control
What is the primary standard used in this experiment .define a primary standard?
It is primary standard is a substance that has a known high digree of purity ,reatively large molar mass ,is nonhygroscopic and reacts in a predic table way.
What is the characteristics of an internal standard?
Internal Standard(IS) is similar in structure and chemical properties to the analyte of interest. We add equal amount of IS to all samples including blank and used to calculate the analyte loss while preparing the sample. IS used for calibration by plotting the ratio of analyte signal to the IS signal.
Why is it necessary to use an internal standard in the GLC assay?
Internal standard is primarily used to increase the accuracy and precision of analytical methods that have large inherent variability. The method is used in chromatography (GC, HPLC) where a compound similar to the analyte of interest is added to the sample and run. By having the analyte and the standard elute in the same run, the run to run variability is eliminated giving more precise results. Obviously one needs to calibrate the responses of the internal standard with that of the analyte. Incidental benefits are saving time and money by having less runs. Hope this is useful.
