Question:
25 grams of sodium hydroxide combines with 18 grams of hydrochloric acid to form 26.5 grams of salt and water. What is the limiting reactant?
Limiting Reactant:
The limiting reactant is the reactant that is fully consumed in a chemical reaction based on the balanced reaction equation. The other reactants are considered to be "in excess". The number of moles of limiting reactant will directly determine the number of moles of all products formed according to stoichiometric coefficients. Using the molar masses of the products you can then find their respective theoretical yields.
