pH is measured using a pH meter, which comprises a detecting unit consisting of a pH sensitive glass electrode and an indicating unit which indicates the pH as shown below. To measure the pH of a solution, the glass electrode is dipped into the solution and the pH is displayed on the screen of the indicating unit. Before measuring the pH of another solution, the glass electrode is rinsed with distilled water and dried carefully with tissue paper. How is the pH reading of the second solution likely to be affected if the glass electrode is not dried with tissue paper in the following cases? (i) if the second solution being measured is acidic in nature (ii) if the second solution being measured is basic in nature
