In a chemical reaction, the limiting reagent is the chemical being used up while the excess reactant is the chemical left after the reaction process.
Before calculating the limiting and excess reactant, it is important to balance the equation first by stoichiometry.
C25N3H30Cl + NaOH = C25N3H30OH + NaCl
Since the reaction is already balanced, we can now identify which is the limiting and excess reagent.
First, we need to determine the number of moles of each chemical in the equation. This is crucial for determining the limiting and excess reagent.
Assuming that there is the same amount of solution X for each reactant
1.0 M NaOH ( X ) = 1.0 moles NaOH
1.00 x 10-5 M C25N3H30Cl ( X ) = 1.00 x 10-5 moles C25N3H30Cl
The result showed that the crystal violet has lesser amount than NaOH. Thus, the limiting reactant in this chemical reaction is crystal violet and the excess reactant is NaOH.
