Answer 1

Answer:

potassium chloride reacts with lead nitrate.

Explanation:

According to solubility rule-

(1) All salts containing nitrate ions ($NO_{3}^{-}$) are soluble.

(2) All salts containing halide ions ($Cl^{-},Br^{-},I^{-}$) are soluble except  halides of $Ag^{+},Pb^{2+},Hg_{2}^{2+}$.

Hence aqueous solution of potassium chloride ($KCl$) reacts with lead nitrate ($Pb(NO_{3})_{2}$) to produce insoluble precipitate of lead chloride ($PbCl_{2}$)

Balanced reaction: $2KCl+Pb(NO_{3})_{2}\rightarrow 2KNO_{3}+PbCl_{2}$

So potassium chloride reacts with lead nitrate.
