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) #

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#.

The balanced chemical equation for the reaction between aqueous lead(II) nitrate, Pb(NO3)2, and aqueous potassium chloride, KCl, is:

[Pb(NO_3)_2 + 2KCl \rightarrow PbCl_2 + 2KNO_3]

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.
