When lead(l) nitrate reacts with sodium iodide, what is the formula for the product lead (lI) iodide?

Answer 1

#"Lead(II) iodide"# #-=# #PbI_2#

#Pb^(2+) + 2I^(-) rarr PbI_2(s)darr#

The fine yellow powder known as "lead(II) iodide" or, less frequently, "plumbous iodide" is insoluble in water.

What does it mean that both mass and charge have been conserved in the given reaction?

The reaction of halides with lead nitrate is often a useful way to identify an unknown halide. #PbCl_2# forms an insoluble white precipitate; #PbBr_2# forms an insoluble cream-coloured precipitate; and #PbI_2# forms an insoluble bright yellow precipitate.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
