More typically, one reagent is completely used up, and others are left in excess,
perhaps to react another day. The reactant that is used up is the limiting reagent.
Which is in excess?" What we will do below is find out which substance runs out
first (called the limiting reagent). Obviously (I hope), the other compound is seen
The reactant that is in excess is the reactant that is not completely used up during
the chemical reaction, that is, there is some of this reactant left over.
The HCl is said to be in excess. ... Calculate which reactant is in excess, when 10
g of calcium carbonate reacts with 50 cm<sup>3</sup> of 2 mol l<sup>-1</sup> hydrochloric acid.
A good way to ensure that one reactant fully reacts is to use an excess of the
other reactant. This is financially efficient when one of the reactants is very cheap.
