Which anion test fits anions: chloride, bromide, iodide
acidify with dilute nitric acid, add aqueous silver nitrate
What is the result of anion test of chlorine, bromine and iodide in solution respectively
white, cream and yellow ppt respectively.
anion test for carbonate and result
add dilute acid, test for CO2 gas. Result: effervescence and CO2 produced
anion test for nitrate in solution and result
add aqueous sodium hydroxide and aluminium foil, warm carefully. Result: ammonia
anion test for sulfate in solution and result
acidify with dilute nitric acid, add aqueous barium nitrate. Result: white ppt
anion test for sulfite and result
add small volume of acidified aqueous potassium manganate. Result: it changes from purple to colourless
