Textbook Problem

Gas evolution was observed when a solution of Na2S was treated with acid. The gas was bubbled into a solution containing Pb(NO3)2, and a black precipitate formed. Write net ionic equations for the two reactions.

Interpretation Introduction

Interpretation:

The net ionic equation for given two reaction should be written.

Explanation

The net ionic equation of the reaction is shown below,

  2H3O+(aq)+S2-(aq)H2S(g)+2H2O(l)

The given compound is Sodium sulfide and acid (hydrochloric acid) which is soluble in water.  In this reaction Sodium sulfide reaction with acid to give hydrogen sulfide (gas evaluation) and water, this is gas forming equation.

  NaS2(aq)+HCl(aq)H2S(g)+NaCl(aq)

Net ionic equation of the given reaction shown below
