Titration Formula – Equation and Problem Solved with Example

With the help of titration, you can always find the unknown concentration value of a solution when it reacts with the solution of known concentration. The solution whose concentration is not known is placed inside the Erlenmeyer flask while other solution whose concentration is known is placed in the burette.

After this, one titrant is added to the solution and the value can be determined with the help of color change. Titration process is usually checked with the help of acids or bases but they are not limited to these two words only. Here is how titration formula is given in the chemistry –

\[\ M_{acid} \times V_{acid} = M_{base} \times V_{base} \]

Where,

Macid = Molarity of the acid
Vacid = Volume of the Acid
Mbase = Molarity of the base
Vbase = Volume of the base

When the titrant or analyte react in the same ration i.e. 1:1 ration then above equation is just more than perfect to find the concentration of unknown solution. In case, ration is not 1:1 then the above equation should be modified a bit. A titration is a popular technique that is frequently used in chemistry labs to find the concentration value of the unknown solution. This process usually involves adding the known solution or titrant to the unknown solution until the reaction is not complete.

For measuring the concentration of the analyte, you should measure the volume of titrant that is used for the reaction. There is also needed Molarity value too for calculating the titration of a solution. Using the titration formula is quite simpler and it is needed frequently for acid-alkali reactions. Here we can combine strong acid with strong base, weak acid with weak base and the strong acid or weak base, weak acid or the strong base etc.
