Salt Analysis Qualitative Analysis Chemistry 2nd Year Practical Acid

Salt Analysis Qualitative Analysis Chemistry 2nd Year Practical Acid Salt analysis (also known as systematic qualitative analysis or qualitative inorganic analysis) involves the identification of the cation and anion of an inorganic salt. this is done by conducting a series of tests in a systematic manner and using the observations to confirm the absence or presence of specific cations and anions. 2% aqueous potassium permanganate. dissolve 0.2 g (or 0.2 ml) of the substance in 2 ml of water (acetone may also be used as solvent). add the potassium permanganate solution dropwise and observe the result. e.g. for a blank determination, count the number of drops added to 2 ml of acetone before the colour persists.

Qualitative Analysis Of Inorganic Salts Acidic Radicals Practical Group 1: take a small amount of the salt in a test tube and add dil. h 2 so 4 solution. warm the solution. if no reaction occurs, then move to group 2 anions. group 2: take a small amount of the salt in a test tube and add conc. h 2 so 4 solution. if no reaction occurs, then move to the individual tests for so 42 and po 43 . Procedure. (a) take 0.1 g of the salt in a test tube and add 1–2 ml of dilute sulphuric acid. observe the change, if any, at room temperature. if no gas is evolved, warm the content of the test tube. if gas is evolved test it by using the apparatus shown in fig.7.1 and identify the gas evolved (see table 7.1). Salt analysis is also called qualitative analysis. it involves the identification of the basic radicals (cation) and acidic radicals (anion) of an inorganic. Salt analysis is an important part of the cbse class 12 chemistry practical examination. with the help of different experiments performed in a laboratory, inorganic salts are separated into different ions. after that, tests are performed to confirm whether certain ions are present or absent in the solution. download: chemistry practical class.
