Question

How do you write a complete balanced reaction of aqueous lead (II) nitrate, `Pb(NO_3)_2`, and aqueous potassium chloride, `KCL`?

Answer 1

`Pb(NO_3)_2(aq) + 2KCl(aq) rarr PbCl_2(s)darr + 2KNO_3(aq)`

Explanation:

How did I know that `PbCl_2` was insoluble? Chemistry is an experimental science and this is something that you must learn. All halides are soluble, EXCEPT for lead(II) chloride, mercurous chloride (`Hg_2Cl_2`), and silver chloride, `AgCl`.
