URGENT HOMEWORK. A farmer has a sack of ammonium nitrate fertiliser. However, he thinks it may be slaked lime, calcium hydroxide instead. How would you prove that it is not slaked lime but ammonium nitrate? Um...do you add sodium hydroxide to ammnium nitrate and warm it to see if ammonia gas evolves so that you know there is ammonium cation present and not slaked lime?

 

Anyway, sorry for always posting homework in other sections. haha, I din't know that here is a place for me to post homework! sorry for the past inconvenience. :)

yup sodium hydroxide would be one test, solubility would be another as would marking the temp as you dissolved it water (the AN will get very cold when water is added) Lime will heat up a little :)
