How do scientific tests help determine the properties of substance?
Wiki User
∙ 6y ago
Scientific tests can help determine substances that appear similar but react differently under the same circumstances. By observing the reactions of the substance using an experiment, you can determine what that substance is made from.

What tests is required to determine the compatibility of donor's and recipient's blood?
crossmatch tests
How will I show a substance containing an element with experiments?
The field of Analytical Chemistry allows you to determine what elements are in a substance. Qualitative analysis identifies which elements are present, while quantitative analysis determines the numerical amount or concentration of each of these elements. There are many ways to perform these tests.
Why is it unnecessary to determine the pH of the remaining acid base solubility tests?
it is unnecessary to determine the pH of the remaining acid-bace solubility tests because it has been confirmed of its property either it is a base or an acid =>
What are the tests for pure red Mercury?
The same as the tests for snake oil. "Red mercury" is a fictitious substance to which a wide variety of miraculous properties are ascribed. See the link to the Wikipedia article for details, but essentially, it's a scam. (There are several reddish compounds of mercury, such as cinnabar; if you were wanting information about one of those, please ask again using its proper name instead.)
What does the baeyers test indicate?
It tests for unsaturation. If the substance being tested is saturated, it will not be reactive; but if it is unsaturated there will be a reaction.
How do scientifics tests help determine to properties of substance?
Characteristic properties are unique for every different substance.
What are the Quantitative tests?
quantitative test is test where it determine the quantity of substance in expereiment
Why is it important to identify an unknown substance?
Because the substance could potentially be extremely toxic or harmful. You must never use an unknown substance in experiments without identifying it first, many tests can be undertaken to determine the cation and anion. These tests include the flame test, solubility tests, precipitate reaction tests and conductivity tests. These do vary depending on the unknown substance.
When testing for chemical properties of a substance will one test be enough?
For the safety of findings it is recommended to do more tests.
What does tests for acidity or basicity mean?
These are tests that are designed to determine whether a substance is acidic (pH less than 7), or basic (pH greater than 7).
Is it possible by testing determine the vintage of the wine?
No, not with scientific tests, but someone with a very well trained palate can sometimes do so.
Can you determine the can's chemical peoperties buy looking at the picture?
no first put it through some tests for chemical properties e.g. is it flammable (put a match under it)
How do forensic scientists analyze unknown powders?
Forensic labs are often called in to identify unknown powders, liquids and pills that may be illicit drugs. There are basically two categories of forensic tests used to analyze drugs and other unknown substances: Presumptive tests (such as color tests) give only an indication of which type of substance is present -- but they can't specifically identify the substance. Confirmatory tests (such as gas chromatography/mass spectrometry) are more specific and can determine the precise identity of the substance.
How scientific were the tests they used back in the Salem witch trials to tell if someone was a witch?
The tests were in no way scientific
Biochemical tests are used to determine what?
to determine rate of growth
What is Scientific modeling?
I suspect you mean the scientific method. Briefly outlined, the scientific method consists of the following tasks: Specify a testable null and an alternative hypothesis based on preliminary tests and observations. Design tests that will determine the validity of the null hypothesis to a specified degree of confidence. Collect data and observations for the tests according to requirements of tests and data sample spaces. Test the hypothesis using collected data and observations. Make conclusions and report on the validity (or not) of the hypothesis. Make recommendation for further studies or applications of the experimental results.
