Analytical Techniques Quiz

A solid substance may contain impurities that are soluble in the same solvent as the main substance and impurities that are not soluble in the same solvent as the substance.

It is essential to obtain chemical substances in pure form before investigating their composition and properties in order to accurately determine their characteristics and behavior, as impurities can affect the results of analytical techniques.

The second type of impurity in a solid substance can be separated using a suitable solvent to dissolve the main compound while the impurities remain undissolved and can be separated by filtration.

<p>Filtration is carried out with the help of a filter paper cone placed in a funnel, where the solution containing the dissolved main compound is passed through the filter paper, leaving the undissolved impurities behind.</p> Signup and view all the answers
