Mention the physical states of all the reactants and products involved in the chemical equation.
a) Substance X is likely to be Lead nitrate, as lead nitrate when reacts with potassium iodide gives yellow ppt.
b) The yellow solid or precipitate consists of Lead iodide.
c) The chemical reactions is characterized by the formation of a precipitate.
d) Balanced chemical equation with the physical state is given below:
$Pb( NO_{3})_{2}( aq) +2KI( aq)\rightarrow PbI_{2}( s) +2KNO_{3}( aq)$
