mdwael:
Oct/nov Paper 6 chemistry question 5 part D "suggest why conc.sulphuric acid should not be used to dry ammonia" and also in the E part I checked mark scheme answer its says that the mistake correction is "tubes should be evened", explanation " liquid would be transfered to gas jar" can someone explain this to  me I didnt understand what liquid theyre talking about.

WARRIOR:
ammonia is basic and sulfuric acid is acidic..they react

tubes should be evened because INLET DELIVERY TUBE is goin inside the sulfuric acid..no it shoudl be outusde so they dont react..!
so that the gs could leave thro the other deliver tube ( outlet)
