What is a Titration calculator?

This titration calculator is specifically designed to help you find out the molarity of a given unknown solution during the titration process.

Students usually have to face great confusion while calculating titrations and most of them come with the same question: how to calculate titrations? However, before moving towards the answer to this most asked question, let's recall the concept of titration!

What is Titration?

Titration, mainly acid-base titration, is an analytical process in which we use a solution(titrant) of known molarity along with an indicator, to neutralize an unknown solution(analyte). From titration calculations, we mean to consider the concentration of a known solution (either acid or base) used to neutralize an unknown solution. In this way, we figure out the properties and behavior of unknown solutions (including molarity, pH, etc.), which in turn, helps to identify that solution.

How titration is performed?

  1. Take the titrant (a solution of known concentration) in a burette using a pipette. After this, take the analyte in a clean titration flask and put it below the burette.
  2. Turn on the tap of the burette in a way so the titrant interacts with the analyte dropwise. However, don't forget to add a colored indicator in the titration flask since it will display the endpoint.
  3. As soon as your titration will proceed further, the color of the analyte will start to change gradually. When the solution changes completely, turn off the burette since it's the endpoint.
  4. Usually, the phenolphthalein is used as an indicator in acid-base titration which remains colorless in neutral and acidic solutions but pink in basic solutions.
  5. Lastly, when you observe the endpoint, note down the concentration of volume of titrant used in the process. Insert the value in the acid-base titration calculator to find out the molarity, volume, and moles of hydrogen and hydroxyl ions.

How does this titration calculator work?

Once you have performed the titration process, this chemical calculator will help you in titration calculations, suppose, the molarity of a given unknown solution using the given formula.

molH×Ma×Va = molOH×Mb×Vb

In the given equation molH is the moles of hydrogen ions contributing to the whole process per one acid molecule while the molOH is that of base molecules.

Similarly, Ma and Mb is the molarity of acid and base, and Va and Vb is the volume of acid and base respectively.

How to use this titration calculator?

  1. Using this titration calculator is quite easy since we have added so many options. Thus, in this way you can change the SI units and known/unknown solutions to customize the options as per your need.
  2. As soon as you open this titration calculator, click on the drag-down icon of the first box. From here, a menu will appear showing numerous options regarding titration calculations. Choose what you want to calculate.
  3. After selecting an entity, suppose the molarity of unknown acid, type volume of acid, and moles of H+ ions it is contributing in the corresponding categories. In the end, set the SI units for each fraction.
  4. Then move towards the section of the known solution. Type molarity and volume of known base and moles of OH- ions it is contributing. Set the SI unit for each fraction and tap on the calculate button.


As soon as you hit the calculate button, the exact values for the unknown solution will come out. For example, if you were looking for the molarity of an unknown solution, you'll get polarity in molar units, which you can further change into millimolar, micromolar, nanomolar, and even picomolar.

Why use this titration calculator?

No doubt, you'll find tons of other tools for titration calculations on the internet but since the spectrum of titration calculations is big enough, not all of them cover everything. For example, some online titration tools are there only for calculating numbers or molarity of H+ or OH- ions donated, while some others only calculate the molarity of unknown solutions.

However, our titration molarity calculator offers you a wide number of choices regarding titration calculations including

  1. Molarity of acid
  2. Molarity of base
  3. Volume of acid
  4. Volume of base
  5. Moles of H+ given by acid
  6. Moles of OH- ions given by the base

Similarly, you can change the SI units for volume and molarity according to your requirements.
