Answer:
potassium chloride reacts with lead nitrate.
Explanation:
According to solubility rule-
(1) All salts containing nitrate ions ([tex]NO_{3}^{-}[/tex]) are soluble.
(2) All salts containing halide ions ([tex]Cl^{-},Br^{-},I^{-}[/tex]) are soluble except halides of [tex]Ag^{+},Pb^{2+},Hg_{2}^{2+}[/tex].
Hence aqueous solution of potassium chloride ([tex]KCl[/tex]) reacts with lead nitrate ([tex]Pb(NO_{3})_{2}[/tex]) to produce insoluble precipitate of lead chloride ([tex]PbCl_{2}[/tex])
Balanced reaction: [tex]2KCl+Pb(NO_{3})_{2}\rightarrow 2KNO_{3}+PbCl_{2}[/tex]
So potassium chloride reacts with lead nitrate.
