A titration calculator is a digital tool designed to assist in determining the concentration of a substance in a solution by performing a chemical titration. It helps simplify complex titration calculations and ensures accurate analysis of chemical concentrations in various chemistry experiments.
Understanding the Concepts of Titration:
“A titration is a quantitative process of adding a solution of known concentration (titrant) to an unknown solution until neutralization occurs”.
In simple words, titration is the best approach to identify the concentration of an unknown solution, which is usually indicated by a color change. In order to be a primary or secondary standard, the titrant solution must meet the necessary requirements.
The Expressions of Titration:
The generally used equation for titration is [M] molarity of the acid ✕ [V] volume of the acid = [M] molarity of the base ✕ [V] volume of the base.
Thus, the normal representation of the titration formula is:
MA × VA = MB × VB
Calculations and Example:
When the titration is completed, the measured values are entered into a formula to determine the substance's molarity. The titration equation is as follows:
nH × Vx × Mx = nOH × Vy × My
- nH – Number of H+ ions contributed
- Vx – Volume of the acid
- Mx – Molarity of the acid
- nOH – No. of OH- ions
- Vy – Volume of the base
- My – Molarity of the base
Assume you have a solution of hydrochloric acid (HCl) with an unknown concentration (Mx), and you want to determine its concentration using a sodium hydroxide (NaOH) solution with a known concentration (My).
You measure the volume of the HCl solution (Vx) that you're going to titrate, let's say it's 0.025 liters (25 milliliters).
You add the NaOH solution drop by drop until the reaction between HCl and NaOH is complete, and you observe a color change indicating the endpoint.
You measure the volume of NaOH solution (Vy) that you added, let's say it's 0.015 liters (15 milliliters).
Now, you know the following:
Vy = 0.015 L
My = concentration of NaOH solution = known value
nH = ? (unknown)
Vx = 0.025 L
Mx = ? (unknown)
nOH = the number of moles of NaOH added, which you can calculate using Vy, My, and the formula nOH = Vy × My.
With nOH known, you can rearrange the titration equation to solve for Mx:
nH = (nOH × Vy) / Vx
Now that you have nH, you can calculate Mx:
Mx = nH / Vx
So, by measuring volumes and knowing the concentration of NaOH, you can determine the concentration (Mx) of the HCl solution.

What are the Types of Titration?
There are many types of titrations that are used in chemical reactions but two of them are the most commonly used in quantitative chemical analysis that are acid-base titrations and redox titrations.
The most common types of titrations are as follows:
- Acid base Titrations
- Redox Titrations.
- Precipitation Titrations.
- Complexometric Titrations.
What else is titration called?
In titration Chemistry, The term “Titration”, is also known as titrimetry.
