Salt Analysis Quiz

Salt analysis, also known as qualitative inorganic analysis, is the process of identifying the acidic (anion) and basic (cation) radicals present in an inorganic salt. It involves preliminary tests (physical properties, solubility), dry tests (flame test, charcoal cavity test), and wet tests (group analysis and confirmatory tests). This systematic procedure helps determine the composition of an unknown salt using characteristic reactions
