Dilute Hydrochloric acid is added then aqueous Barium Nitrate, a white precipitate forms. Which anion is present?
Sulfate (SO42−)
Nitrate (NO3−)
Carbonate (CO32-)
How would you determine whether Nitrate (NO3-) ions are present in a solution
Add Acid -> Effervescence -> Carbon dioxide released (turns lime water milky)
Add Aq. Sodium hydroxide -> add aluminium foil and warm gently -> Ammonia released (turns damp red litmus paper blue)
Add dilute Hydrochloric acid -> Add Aq. Barium nitrate -> White precipitate
Which of these is untrue for testing for halides in solution
Iodide - White ppt.
Chloride - Cream ppt.
Bromide - Yellow ppt.
Dilute nitric acid is added to a substance and then silver nitrate, a white precipitate forms, what anion is present?
Iodide
Carbonate
Sulfate
Bromide
Nitrate
Chloride
To test whether a carbonate anion is present, a dilute acid is added and effervescence is observed and Oxygen released.
