SOLUBILITY TEST
Aim: To determine nature of given compound using solubility test. Requirements: Beaker, Solvents , compound, Test tubes , Testtube stand , glassrod, Molisch regent , litmus paper. Procedure: 1)Take some amount of sample dissolve it in the solvent. (Solvents used are water, NaOH, NaHCO3 , HCl.) 2)Check the given compound is soluble in which solvent. If it is soluble in HCl- the given compound is water insoluble basic, NaHCO3 then water insoluble strong acid, NaOH then water insoluble weak acid, In water the compund is water soluble neutral/acidic/basic. Theory:- When mixture of definite quantity of given solute and specific amount of given solvent forms a homogeneous amount liquid the former is said to be soluble in the latter. The study if solubilty behavior of an unknown substance in various liquids ie water , sodium hydroxide, sodium hydrogen carbonate and HCl. 1) compund +H2O--- ▪︎If it solublizes in water then perform litmus test •If blue litmus turns red it is water soluble acid
