Explanation:

If the glass electrode is not dried with tissue paper after rinsing with distilled water, the residual water droplets on the electrode surface can affect the pH reading of the second solution. Water can dilute the solution being measured and introduce an additional source of ions, potentially altering the pH reading. The water droplets can also introduce a small amount of impurities or contaminants, which may interfere with the accurate measurement of pH. Therefore, it is important to dry the glass electrode carefully with tissue paper to ensure accurate and reliable pH measurements for the second solution.

The pH reading of the second solution may be impacted by water droplets that remain on the glass electrode after it has been rinsed with distilled water if it has not been dried with tissue paper.

• The pH reading may change if water is added because it can dilute the solution being measured and add another ion source.
• A minor quantity of pollutants or contaminants may be introduced by the water droplets, which could prevent a precise pH reading.
• To guarantee precise and trustworthy pH measurements for the second solution, it is crucial to gently dry the glass electrode using tissue paper.
• In other terms, a pH metre detects the acidity or alkalinity of a solution by measuring the activity of hydrogen ions in solutions.
• In the end, the pH level, which typically ranges from 1 to 14, is used to describe the level of hydrogen ion activity.

Hence, the pH reading of the second solution may be impacted by water droplets that remain on the glass electrode after it has been rinsed with distilled water if it has not been dried with tissue paper.
