Question

Predict whether a precipitation reaction will occur when aqueous solutions of pbcl2 and (nh4)2s

Answer 1

Answer : YES, The precipitation reaction will occur.

Explanation : When we mix the aqueous solutions of Lead chloride and Ammonium sulfide a reaction will occur which is stated below :


`PbCl_(2) +(NH_(4)) _(2) S ----\ \textgreater \ PbS + 2[ (NH_(4))Cl]`

The major product that is formed is Lead sulfate which is black in colour.

Once the reaction is complete one can observe a black precipitate getting obtained.
