Question

you are given a solution of lead nitrate. use any of the solution used in this experiment to form a white precipitate of lead chloride. write down the equation

Answer 1

We have as a reagent a salt, lead nitrate (Pb(NO3)2), and an unknown solution that gives us as a product lead chloride (PbCl2). That is, the solution must contain chlorine.

If a chlorine solution is used we will have the following reaction:

`Pb(NO_(3)2)+2Cl^-\rightarrow PbCl_2+2NO^-_3`

So, with a chlorine solution, we will have a white precipitate of lead chloride.
