Question

Aqueous potassium chloride will react with which one of the following aqueous solutions to produce a precipitate? calcium nitrate sodium bromide lead (II) nitrate barium nitrate sodium chloride Write the balanced molecular equation for the reaction that occurs IN PROBLEM 1. the mixing of which pair of reactants will result in a precipitation reaction? Ba (NO_3)_2 (aq) + Na_2 CO_3 (aq) K_2 SO_4 (aq) + Cu (NO_3)_2 (aq) NaClO_4 (aq) + (NH_4) _2 S(aq) NH_4 Br (aq) + NH_4 l (aq) Write the balanced molecular equation for the reaction that occurs IN PROBLEM 2

Explanation / Answer

Ans 1 C lead nitrate reacts with potassium chloride to form a precipitate others will form salts which are soluble in water.

The reaction will be

Pb(NO3)2 + 2 KCl --> PbCl2 + 2 KNO3

Lead chloride is the precipitate
