Titration Calculator

This calculator helps the user to estimate the concentration of the solution by titration. It is used for titration-based test kits where the concentration ratio from the torrent described in the instructions is suspected.

Titration Calculator

Our titration calculator helps you identify the solution properties (such as pH) during an experiment based on acid-based titration, or when there is an unknown solution while doing fieldwork. Using solutions with unknown solutions and color indicators, we measure the extent to which a solution is needed to neutralize an unknown solution, indicating a change in the indicator, which we use to determine the unknown solution

How to calculate titrations?

An acid or a base when dissolves in water, their H⁺ and OH⁻ ions respectively dissociate, shifting the natural self-ionisation equilibrium of water (2H₂O ⇌ H₃O⁺ + OH⁻), making the solution more acidic or more basic. At pH 7, the concentration of H₃O⁺ ions to OH⁻ ions is a ratio of 1:1 (the equivalence point). When we do titration, we usually have a solution of a known volume but unknown ethics (analyzer), including color indicators. Phenolphthalein is added. The color of the indicator will change when a ratio of 1: 1 is obtained through its titration curves. By adding either an acid or a base, which is known to be a titrant, and measuring how much it needs to cause this change, we can put the ethics of the unknown into practice, using the following equation. nH*Ma*Va=nOH*Mb*Vb where: # nH = number of H+ ions contributed per molecule of acid, # Ma = molarity of the acid, # Va = volume of the acid, # nOH = number of OH- ions contributed per molecule of base, # Mb = molarity of base, and # Vb = volume of the base.

Titration curves

A titration curve is a plot of the concentration of the analyzer in which the pH vs. the volume of the titrant is usually added to the acid base titration at a particular point of experience. Of acid-base titration, this curve tells us whether we are dealing with a weak or strong acid / base.
