Question

What are the solubility rules for the following anions? S032, PO43-, NO3-,r Which of them would form precipitates when exposed to Ba²+, Ag'? Which of following anions would react with acid? SO,2", PO43-, NO3-, If Ag2SO3 () is added to water, will it dissolve? What about if it is added to HNO3(aq)? The brown ring test will determine the presence of what anion in solution? What color is a Agi precipitate? When completing this lab, it is important to use good analytical technique. What are 3 tenets of good analytical technique? What are two ways to mix up the liquids in a test tube?

Answer 1

# Sombility rules • All So2- are insoluble except those of Nint 4 alkali masted cation of • All Pons are insoluble except those NH4 & alkali mutado cation • All Nog are souble • All I are soluble except Ag, Pb & Hg (!). Chart so ² - Pon3- No I- Ba 21 Ppt ppt (somble) Copuble) PPь Pet PPE (soluble) # As, Sog will not dissolve in water It will be soluble when HNOglaq) will be added since it will form AgNO3 which is soluble # is for the poresence of Brown ring test Nozion # Ag I poste precipitate is yellow in colour
