For the calculating change in pH question, some of the volumes of acid required were very very small. The smallest volume that can be reasonably transferred with pipetteman is 2 microliters (2 x 106 liters) If the volume of acid that needs to be added is so small that there is no equipment available to measure and transfer the correct volume of acid, what could be done to successfully adjust the pH? a) Use a less concentrated acid to adjust the pH so the required volume would be larger b) Use a more concentrated acid to adjust the pH so the required volume would be larger c) Use a less concentrated acid to adjust the pH so the required volume would be smaller d) Use a more concentrated acid to adjust the pH so the required volume would be smaller

To successfully adjust the pH, as there was no equipment to measure and transfer the correct volume of acid, then A. Use a less concentrated acid to adjust the pH so the required volume would be larger.

What is an acid?

This is a substance that changes the taste in water solution and changes blue litmus paper to red, reacts with some metals to liberate hydrogen, reacts with bases to form salts, and promotes chemical reactions (acid catalysis).

Hence because there was no equipment available to measure and transfer the correct volume of acid, the best and safest and most successful thing to be done is to use a less concentrated acid to adjust the pH so the required volume would be larger.
