Chemisty help... 'halogen precipitates'

Any help would be apppreciated, as i am unsure of the answer on my homework.
"Compare the precipitates formed (lead fluoride, lead chloride, lead bromide, and lead iodide) by listing their similarities and differences."
Thanks in advance.
You can compare their reaction with ammonia, colours, light effects on them, and so on.

For instance, AgCl will dissolve more easily than AgBr in ammonia. Can you guess why?
