Qualitative Analysis Or Salt Analysis For Acid Radicals Some Special Also, some salts can be identified by observing their texture and appearance (for example, calcium carbonate has the texture of powdered chalk). therefore, visiting your chemistry laboratory and physically examining the salts may help you quickly analyze the salt in the practical examination. list of common cations (basic radicals) for salt. 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 Formulas Complete List Formulae Sheet For Salt Analysis #salt analysis #qualitative analysis #acid radicals. Salt analysis is also called qualitative analysis. it involves the identification of the basic radicals (cation) and acidic radicals (anion) of an inorganic. In qualitative inorganic analysis of basic radicals, hydrochloric acid is preferred to nitric acid for preparing a solution of given substance. this is because: (1) nitrates are not decomposed to sulphides (2) nitric acid contains nitrogen (3) hydrochloric acid is not an oxidising agent (4) chlorides are easily converted to sulphides. The acidic radicals for simple salts were divided into 3 groups according how it reacts with strong and diluted acids 1. dilute hcl group: salts in this group produce specific gases when react with dil. hcl, acidic radical of this group: acidic radicals symbol شلا reaction of salt with group reagent co 3 تانوبرك na 2 co 3.
