In a chemical reaction the limiting reagent is the compound totally consumed when the reaction is complete.
It is 2,4-dinitrophenylhydrazine with the chemical formula C6H6N4O4.
K2(HgI4)
The limiting reagent is entirely used at the end of a chemical reaction.
The chemical composition remain unchanged.
