What is the limiting reactant?

Question

Using the quantaties 25 ml .0200 M KIO3 solution and 1.00 g KI solution, Show that KIO3 is the limitng ractant in the equation:

6H+KIO3+8KI--> 9K+3I3+3H2O

I do not fully understand how to determine the weight of the products or find out how it is the limiting reactant.

Answer 1

Limiting Reactant - The reactant in a chemical reaction that limits the amount of product that can be formed. The reaction will stop when all of the limiting reactant is consumed.
Please visit for ready reference for the example you have given:

90.0 g of FeCl3 reacts with 52.0 g of H2S. What is the limiting reactant? What is the mass of HCl produced? What mass of excess reactant remains after the reaction?

NOTE: The limiting reactant is the reactant that limits the amount of product that can be formed and is completely consumed during the reaction. The excess reactant is the reactant that is left over once the reaction has stopped due to the limiting reactant. See notes limiting reactant.

Answer 2

Try to find out the moles.
