When ammonia, NH3, is produced in a school or college laboratory, it is usually dried before being collected. Which drying agents may be used to dry ammonia? 1 calcium oxide, CaO 2 phosphorus(V) oxide, P4O10 3 concentrated sulfuric acid, H2SO4

    What reactions do the drying agents undergo with water?

    1) hydration since it becomes calcium hydroxide 3) dissociation? 2)umm p4O10 just gets converted to phoshporic acid Is this what you ask?

    yep. so do you think they'll be any side reactions? which drying agent wont cause a reaction with ammonia?

    You're asking if there are any other products formed in above reactions with water?

    Not with water but between ammonia and the drying agent (now hydrated)

    nope. you said that p4O10 just gets converted to phosphoric acid wouldn't that react with ammonia?

    Yeah absolutely because we need a dried NH3 not the one reacted.
