| August 11, 2021 | education
Write down the equation of the chemical reaction of hydrogen sulfide with a solution of lead nitrate (//) in molecular, full and abbreviated ionic form. Note the signs of a reaction.
H2S + Pb (NO3) 2 = PbS (sediment) + 2HNO3
H2S + Pb2 + + 2NO3- = PbS (sediment) + 2H + + 2NO3-
H2S + Pb2 + = PbS (sediment) + 2H +
Hydrogen sulfide weakly dissociates in aqueous solutions, therefore, in the equations it is written in molecular form.
A sign of the progress of the reaction is the precipitation of a dark precipitate of lead sulfide.
