This is the value found from actually performing some experiment, rather than the theoretical value, which is found from reference material. This could be something like 'determine the density of water'.
- You can look up in a reference table the density of water at a given temperature - this is the theoretical value.
- Now you perform the experiment. You measure the temperature, then you get a graduated cylinder and measure the mass of the empty cylinder. Now fill the cylinder with a specific amount of distilled water. Measure the mass of the filled cylinder. Subtract empty mass to get the mass of the water. Now density equals mass/volume, so divide.
This value obtained from the experiment is the experimental value.
Experimental value in chemistry refers to a measurement or result obtained through conducting scientific experiments in a controlled setting. It is used to compare with theoretical values and assess the accuracy of experimental methods and instruments in determining physical and chemical properties of substances.

What is percentage error in a chemistry experiment?
Percentage error in a chemistry experiment is a measure of the difference between the measured value and the actual value, expressed as a percentage of the actual value. It helps to determine the accuracy and precision of the experimental results. A lower percentage error indicates higher accuracy, while a higher percentage error indicates lower accuracy.
Why did Paul J. Flory win The Nobel Prize in Chemistry in 1974?
The Nobel Prize in Chemistry 1974 was awarded to Paul J. Flory for his fundamental achievements, both theoretical and experimental, in the physical chemistry of the macromolecules.
What does RTP stand for in chemistry?
RTP stands for Room Temperature and Pressure in chemistry. These are standard conditions used when describing experimental procedures and results.
What do you mean by ppt in chemistry?
In chemistry it means precipitate.
What effect on the experimental value will the use if wet or moist ice have?
The answer depends on what the experiment is.
The difference between an accepted value and an experimental value is called?
In science, and most specifically chemistry, the accepted value denotes a value of a substance accepted by almost all scientists and the experimental value denotes the value of a substance's properties found in a localized lab.
What is literature value in chemistry?
Literature value in chemistry refers to the accepted or established value of a physical or chemical property that can be found in scientific literature. It serves as a point of reference for comparing and validating experimental results obtained in the laboratory. Comparing experimental results to literature values helps scientists assess the accuracy and reliability of their measurements.
What is the difference between true value and experimental value?
true value is something that is true and experimental value is some thing that has been experimental with
What is difference between the accepted value and the experimental value?
the answer is error or experimental error.
Experimental value minus the accepted value is called the?
The difference between the experimental value and the accepted value is known as the experimental error. It helps to quantify how closely the experimental result matches the true value.
How do you get the experimental value of a rectangle?
A rectangle has no value - experimental or otherwise. Its area has a value, its perimeter, its aspect have values.
Why is experimenral value different from literature value in chimestry?
Experimental values may differ from literature values in chemistry due to errors in measurement techniques, equipment calibration, sample purity, or human error in performing experiments. Additionally, variation in experimental conditions, such as temperature, pressure, or reaction time, can also contribute to discrepancies between experimental and literature values.
Why the experimental value of specific heat capacity is higher than the standars value?
Experimental errors would cause the experimental value of specific heat capacity to be higher than the standard value.
What did the chemist Jabir ibn Hayyan do?
He introduced experimental investigation in chemistry
What is weighted average in chemistry?
The meaning in chemistry is identical to the meaning in statistics; weiggted averaging is useful in the processing of experimental data.
What has the author Samuel Morris written?
Samuel Morris has written: 'The comparative value of different specimens of iodine for use in chemical measurements' -- subject(s): Accessible book, Iodine 'Experimental procedures in general chemistry' -- subject(s): Chemistry, Laboratory manuals
What is a percentage error?
The percentage error is how accurate your experimental values compared to the accepted value. The equation is: [(experimental value - accepted value) / accepted value] x 100
