Do you know what acid-base titration is? In this article, we will discuss the procedure of acid-base titration in detail. This process is used to determine the concentration of an anonymous acid or base solution. It can also be used to calculate the amount of a known reactant in a reaction. The procedure for conductometric titration of a weak acid and strong base is slightly different from the procedure for conductometric titration of strong acid and strong base. We will discuss both procedures in detail below.
What is acid-base titration?
An acid-base titration is a type of analytical chemistry that is used to determine the concentration of an unknown acid or base. This type of titration can be conducted using either a conductometric or volumetric method. In a conductometric titration, the change in electrical conductivity is monitored during the reaction between the acid and base. Whereas in volumetric titration, the change in volume is monitored.
Conductometric Titration Of A Weak Acid And Strong Base Procedure
The most common type of conductometric titration is the weak acid and strong base procedure. In this procedure, a known volume of acid is added to a known volume of base. The mixture is then titrated with a standard solution of the base until the endpoint is reached. The endpoint is the point at which the conductivity of the solution changes from being acidic to being neutral.
Procedure For Conductometric Titration Of Strong Acid And Strong Base
The procedure for conductometric titration of a strong acid and strong base is similar to that of a weak acid and strong base. However, in this case, the endpoint is reached when the conductivity of the solution changes from being basic to being neutral.
Both of these procedures can be used to accurately determine the concentration of an unknown acid or base. However, it is important to note that the choice of method will depend on the nature of the acid or base being analysed. For example, if the acid is a strong acid, it is more accurate to use the conductometric titration of a strong acid and strong base procedure. Whereas if the base is a weak base, it is more accurate to use the conductometric titration of a weak acid and strong base procedure.
No matter which method you choose, acid-base titration is a simple and effective way to determine the concentration of unknown acid and base.
Experimental Procedure Of Acid-base Titration:
Here is the step by step procedure for the conductometric titration of a weak acid and strong base:
– First, take a burette and fill it with the standard base solution.
– Next, take a conical flask and add 25ml of the unknown acid solution to it.
– Now, start the stopwatch and quickly add the base solution from the burette to the flask.
– Continue adding the base solution until you reach the endpoint. The endpoint is when the colour of the solution changes from pink to colourless.
– Once you reach the endpoint, stop adding the base and note down the volume of base used.
– Repeat the experiment two more times and calculate the average volume of base used.
The Procedure Of Acid-base Titration is a simple yet important experiment in acid-base chemistry. By following the steps above, you can easily conduct this experiment and obtain accurate results.
This procedure can be used to determine the concentration of an unknown acid solution. It is also useful for studying the properties of acids and bases.
Conclusion:
Procedure Of Acid-base Titration is the most commonly used method to determine the acidity or basicity of a solution. This type of titration is conducted by measuring the conductivity of the solution being titrated. The procedure for conductometric titration of a weak acid and strong base, as well as the procedure for conductometric titration of strong acid and strong base, are both relatively simple and can be easily carried out with the proper equipment. With a little practice, anyone can become an expert at conducting this type of titration. Thanks for reading!
