|Ammonia is a gas which has a characteristic sharp, penetrating odor.
Part of the irritation it causes when smelled is due to its being a base and changing the
pH of your mucous membranes.
Pure Ammonia liquifies at -33.5șC. It must be kept in pressure or cryogenic tanks.
The "ammonia" you commonly see are aqueous solutions. In the laboratory, concentrated ammonia is a 14-15 M solution. Household ammonia generally run about 5% NH3.(can you calculate its molarity?)
In 1996 over 35 billion pounds of ammonia were produced in the United States! It is produced by the Haber Process.
3 H2 + N2 -------> 2 NH3
is carried out at high temperature and pressure and in the presence of a catalyst
|In this experiment...
you will prepare ammonia by the reaction of ammonium nitrate with sodium hydroxide.
NH4NO3 + NaOH -----> NaNO3 + H2O + NH3
for ammonia, you will use another important principle:
In this experiment to test for the absence of ammonia
1. Based on last week's experiment, you should be able to answer the following.
A bottle of ammonia has an assay of 29.6% ammonia by weight. If its Specific Gravity is .90, calculate its Molarity.
2. You pour pure liquid ammonia into a beaker(in the HOOD!). Will frost form on the outside of the beaker while the ammonia inside boils?
