The substance that releases the greatest amount of ions will have the greatest attractive forces within its solution, resulting in a reduced freezing point.
K₂SO₄ yields 3 ions
NH₄I yields 2 ions
CoCl₃ yields 4 ions

Freezing points:
CoCl₃ < K₂SO₄ < NH₄I

Answer:

limiting reactant

Explanation:

<em>The term that will be used to describe zinc in this case is </em><em>limiting reactant.</em>

A limiting reactant is a reactant that determines the amount of product formed in a chemical reaction. They are often stoichiometrically smaller of all the reactants in a reaction and once they are used up during, the reaction stops.

In this case, the zinc metal in the reaction is completely consumed, making the hydrochloric acid to be in excess. The zinc thus determines the amount of the products formed,
