Question

How can I calculate the titration of a weak acid and a strong base?

Answer 1

The basic concept of physical chemistry carried out in the laboratory that is the titration process which is dependent on the calculation of pH values and also the value at the equivalence point.

Complete step by step answer:
- In the previous classes of chemistry, we have come across the concepts of the physical chemistry which we carry out in the laboratory and the most common experiment that is the titration process.
Let us see what titration means and how can we determine the values for the weak acid and a strong base.
- Titration is the common laboratory experiment of quantitative analysis to determine the concentration of the identified analyte.
- Steps to calculate the titration of weak acid and strong base are as follows,
a) In the beginning find the pH of the given solution.
b) Second step involves the determination of the equivalence point of the titration.
c) This step involves the calculation of pH of the titration using Henderson – Hasselbalch equation
d) This step involves the final calculation of molarity of the solution and then followed by the concentration of hydroxide ion and here is the end point.

Note: Note that the equivalence point and the end point are the different terms. Equivalence point occurs before the end point where the equivalence point is the point where the chemical reaction comes to an end and the end point is where the colour change occurs.
