Limiting Reagent Calculator: Thinking on how to find the limiting reagent easily?If so, this tool is for you. This calculator assists you to calculate limiting reagent that goes for completing during reaction and makes a limited amount of product.

This is the free tool that provides you with the information like definition, formulas, steps and some solved examples. Read on to know more!!

## Define Limiting Reagent?

In chemistry, it is a particular reactant that gets consumed totally when the reaction is completed is known as limiting reagent. According to the stoichiometry, a fixed amount of reactants will be required for the completion of the reaction.

### How to Find Limited Reagent?

Here are the guidelines that are given below to calculate the limited reagent. Look into the guidelines carefully.

• Firstly, write down the reaction that was given.
• Balance the equation, by providing some data.
• Give the values for thr equation.
• Finally, get the result easily.

Example: 90g of hydrochloric acid is added to 90g of zinc. Find the volume of hydrogen gas evolved under standard laboratory conditions.

Solution:

The chemical equation for these reactions is given below.

2HCl(aq) + Zn(s) → ZnCl2(aq) + H2(g)

It is formed in excess so the limiting reagent here is hydrochloric acid.

73g of HCl = 22.4l of H290g of HCl = yL of H2

y/22.4 = 90/73

y = (90 x 22.4)/73

y = 27.61L

Therefore, 27.61L of H2 is produced under standard laboratory conditions.
