In summary, titration is a laboratory technique used to determine the concentration of a substance in a solution. It is used in testing pure sulphuric acid to accurately determine its concentration, which is important in many industrial and scientific applications. The equipment needed for titration includes a burette, pipette, conical flask, and a standardized solution of a base. To perform titration, a measured amount of the acid is placed into a conical flask and a few drops of an indicator are added. The standardized base solution is then slowly added until the indicator changes color, indicating that the acid has been neutralized. Some common sources of error in titration include incorrect measurement of solutions and incomplete mixing. Careful adherence to correct procedures and precise

FAQ: Why is pure sulfuric acid unsuitable for direct standard solution preparation?

What is titration and how is it used in testing pure sulphuric acid?

Titration is a laboratory technique used to determine the concentration of a substance in a solution. In the case of pure sulphuric acid, titration is used to determine the exact concentration of the acid in a given sample.

What equipment is needed for titration of pure sulphuric acid?

The equipment needed for titration of pure sulphuric acid includes a burette, pipette, conical flask, and a standardized solution of a base (such as sodium hydroxide) as the titrant.

How do you perform titration of pure sulphuric acid?

To perform titration of pure sulphuric acid, a measured amount of the acid is placed into a conical flask and a few drops of an indicator (such as phenolphthalein) are added. The standardized base solution is then slowly added from the burette until the indicator changes color, indicating that the acid has been neutralized. The volume of base solution used is then used to calculate the concentration of the acid.

What is the purpose of titrating pure sulphuric acid?

The purpose of titrating pure sulphuric acid is to accurately determine its concentration, which is important in many industrial and scientific applications. Knowing the exact concentration of the acid allows for precise measurements and calculations in experiments and manufacturing processes.

What are some common sources of error in titration of pure sulphuric acid?

Some common sources of error in titration of pure sulphuric acid include incorrect measurement of the acid or base solutions, incomplete mixing of solutions, and variations in the color change of the indicator. It is important to carefully follow the correct procedures and use precise measuring techniques to minimize these errors.
