Anion Test Flashcards
Carbonate ion: Test
Add dilute hydrochloric acid to the salt
Carbonate ion: Observation
Carbon dioxide evolved which turnd limewater milky
Carbonate ion: Confirmatory Test
Add magnesium sulfate to a fresh solution. White percipitate forms.
Carbonate ion: Chemical equation
CO3 + 2H -> CO2 + H2O
Mg + CO3 -> MgCO3
Hydrogencarbonate: Test
Add dilute hydrochloric acid
Hydrogencarbonate ion: Observation
Carbon dioxide evolved which turns limewater milky
Hydrogencarbonate ion: Confirmatory test
Add magnesium sulfate to a fresh solution
Nitrate ion: Test
Add fresh FeSO4 solution and concentrated H2SO4(sulfuric acid) to the solution, at an angle.
Nitrate ion: Observation
Brown ring observed
Chloride ion: Test
Add silver nitrate (AgNO3) to solution
Chloride ion: Observation
White percipitate is formed
Chloride ion: Confirmatory test
White percipitate dissolves in ammonia solution
Chloride ion: Chemical equation
AgNO3 + NaCl -> AgCl
Sulfite/Sulfate ion: Test
Add barium chloride (BaCl2) to solution
Sulfite/Sulfate ion: Observation
White percipitate is formed to make barium sulfite
White percipitate is formed to make barium sulfate
