Question

While doing titration we take concurrent reading like.

Reading..........Concurrent reading

3.6
3.4=====> 3.4
3.4
Why don't we take the mean value as we do in physics?

Answer 1

In titration, we don't take the mean value because consecutive readings of the same value indicate that the reaction has reached its endpoint. Additional readings will not provide any additional information.

Step-by-step explanation:

In physics, taking the mean value is often done to account for experimental errors and obtain a more accurate result. However, in titration, we don't take the mean value because consecutive readings of the same value indicate that the reaction has reached its endpoint. It means that the reaction is complete, and further titrant addition will not result in any significant change.

To illustrate this, let's say we are titrating an acid with a base, and the reaction reaches its endpoint when the pH of the solution is 3.4. In this case, if we take two consecutive readings and both show a pH of 3.4, it indicates that the reaction has fully completed, and there is no need to take further readings or compute an average.

Therefore, in titration, we don't take the mean value because the consecutive readings show that the reaction has reached its endpoint, and additional readings will not provide any additional information.
