Our online limiting reagent calculator tool helps us to calculate the limiting reagent easily in fraction of seconds. For using this calculator tool, give the inputs in the input field and tap the calculate button. This calculator tool is user friendly and easy to use.

### 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.

### FAQs on Limiting Reagent Calculator

1. What are the steps to use limiting reagent calculator?

Here are the steps to use the limiting reagent calculator that are given below.

• Give the inputs in the input fields.
• Click on the calculate button.
• Finally, get the answer easily in fraction of seconds.

2. How limiting reagents are used in daily life?

If you are eating bread and jam. The bread will end soon but the jam is still remaining in the jar. Here, bread is the limiting reagent and the jam is the excessive agents.

3. What is limiting reactant?

Limiting reagent is the amount of product that is produced when a reactant is in a chemical reaction.
