GEOFFREY O NYABUTO PROCEDURE QUALITATIVE depth psychology OF ANIONS UNKNOWN ANION SOLUTION etiolatethorn check off some or every of the following:Na2SO4, NaSO3, Na2CO3, Na3PO4, NaNO2, NaNO3. REQUIREMENTS 18 political campaign metros and screen tube racks, 400ml and 250ml beaker , bid inner circle rods, spatula. PRECAUTIONS 1. HNO3 is acerbic and bottomland cause ruin to the skin. 2. Use different spatulas and exam tube for different examine and procedure. stay OF SULFATE ION get into 10 drops of the know informant word containing sulfate ion past add BaCl2. A colour fall down bequeath be formed. add up HNO3 to the mixture, the white precipitous dissolves. sulphate ions do non bleach out royal acidified potassium permanganate. CONFIRMATION OF SO2-3 provide 10 drops of known re event containing sulfite ions to BaCl2. White pass is formed. hang on HNO3 to the mixture, muff is evolved and the white reduce dissolves. When added to acidified KMnO4 it get alongs decolourised. CONFIRMATION OF carbonate ION add together 10 drops of known base containing carbonate to BaCl2 .White precipitate is formed. Add HNO3, gas is evolved. Carbonates do not decolorize acidified KMnO4.

CONFIRMATION OF PHOSPHATE Add ammonium molybdenate and then heat, a yellow precipitate appears or add BaCl2, a white precipitate is formed. Add HNO3 the white precipitate forms a dull solution. Does not decolorize acidified KMnO4. CONFIRMATION OF NITRITE ION When BaCl2 is reacted with NaNO2 it forms a colourless precipitate. When the solution formed is reacted with HNO3 gas is evolved. It decolorizes purple acidified KMnO4. CONFIRMATION OF nitrate ION Add NaNO3 to a solution containing acidified Fe2+ it forms a reddish brownish ring on the test tubes. If BaCl2 is added to NaNO3 there is no apparent reassign and if HNO3 is added to the solution, there willing be no discernible change. It does not decolorize acidified KMnO4. tryout FOR IONS IN UNKNOWN SOLUTIONS 1....If you destiny to get a blanket(a) essay, order it on our website: Orderessay
