Test for sulfate lons test is done in solution, If you howe on solid you must first dissolve in pure water. 1. aciclify the solution with dilute hydrochloric acid 2. add banum chlonde solution 3. you will see on white precipitorte if sulfonte is present. JON TESTS - Precipitation is formed by Sulfate and bonum lons clumping together Ba²+ (aq) + SO4²- (ong) Ban Soy (s) (insoluble) Role of hydrochlonc acid, banum sulfonte is not the only insoluble compound bamum carbonate is aswell so will also produce on white precipitonte so dilute acid is used to bind with carbonote ions in solution forming CO₂ + H₂0. not every dilute acid can be used eg. sulfunc acid contains sulfate lons so will air- eady form on white precipitonte Test for carbonate lons - 1. add engedvs acid to suspected solution, if positive CO₂ will form 2. test the gas by bubbling it through lime worter, if positive lime woter will tum cloudly (O₂(g) + Ca(OH)₂ (aq) (on (03 (5) + H₂0 (1) Calcum carbonate is formed white precipitate (ca(03) carbonate compound • Cloudy lime water Test can also be used for hydrogencarbunate lon Test for ammonium lons 1. add sou wum hydroxide into the solution (NaOH) Nhut + NOOH NH,+H2O 2. war the mise ture. 3. to test the gas produced with damp red litmus paper If positive red litmus...

paper will tur blue. Test for Halide lons Halide lons can be identified in an unk nown Solution by dissolving so- lution in nitric acid then adding silver nitrate solution drop wise IF NH13 is present nitnic acid is to prevent any false positives from carbonate ions precipitenting out with silver ions nitric acid reacts with carbonate ions producing (0₂ and H₂0. Halide lons + silver nitrante solution - Ag+ (aq) + X (ong) Ag X (s) X = Halide lon Silver Chlonde (AgCl) = Silver Bromide (Ag Bv) Silver lodide (AgI) = = White Pr. cream Pr. Yellow Pr. white precipitonte cream precip itonte yellow precipitente. Adding Ammonin 1 because white cream and yellow look similar in colour ammonios. is often an follow up test to determine which halide ion is present If precipitante dissolves in dilute ammonio, then unknown is Chlonde If precipitonte does not dissolve in dilte ammonios but concentrented ammonin, the unknown halide is bromine If precipitate does not dissolve in dilute ammonia or concentrated ammonia, then unknow halide is lodine.
