The percent yield of alum is calculated based on the starting quantity of aluminum. Why can't the quantity of sulfuric acid be used to calculate the percent yield

Sagot :

The quantity of sulfuric acid may not be used because sulfuric acid is excessive and aluminum is limiting.

Limiting reactants

Limiting reactants in reactions are reactants that are present in lower stoichiometric quantities in comparison with other reactants.

Thus, limited reactants determine how far the reaction can go in terms of producing products.

Thus, the percent yield of alum might have been calculated based on the starting quantity of aluminum because the latter is the limiting reactant of the reaction.
