Question

What is the net ionic equation of the following chemical reaction? Enter your answer in the space provided. Include the charge and the state of matter. For example, an aqueous sodium ion would be entered as Na+(aq) and solid silver chloride would be entered AgCl(aq).

Pb(NO3)2(aq) + 2NaCl(aq) --> 2NaNO3(aq) + PbCl2(s)

Answer 1

Answer:

pb entered as pb+2 and nitrate as no3- ;

Answer 2

Given: Pb(NO3)2(aq) + 2NaCl(aq) --> 2NaNO3(aq) + PbCl2(s)

To Find: Net ionic equation of the given chemical reaction.

Explanation:

$Pb(NO_{3} )_{2} (aq)+2NaCl(aq) -->2NaNO_{3}(aq) + PbCl_{2} (s)$

In the given reaction, Lead nitrate salt and Sodium chloride salt will dissociate into their ions.

$Pb(NO_{3})_{2} (aq) --> Pb^{+2}(aq) + 2NO_{3}^{-} (Aq)$

$2NaCl(aq)--> 2Na^{+}(aq) + 2Cl^{-} (aq)$

The salt lead chloride has very low solubility in aqueous phase. So it will remain undissociated.

Lead chloride will precipitate out from the reaction mixture. All the other ions will remain in solubilized state in aqueous reaction phase.
