Question
2. The pH of a solution is a measure of its acidity. The table on the next page shows pH values and their meaning. The partial pseudocode below the table designs a program that displays the acidity level that corresponds to a solution’s pH entered by the user. The decision structure part of the program is missing. It should display the correct solution from the right column of the table. Fill in the missing decision structure (5 points)
[Hint: See pages 157-163 in the textbook]
| pH Range | Solution |
| pH < 3 | Very acidic |
| 3 <= pH < 7 (pH is >= to 3 and < 7) | Acidic |
| pH = 7 | Neutral |
| 7 < pH < 12 (pH is > 7 and < 12) | Alkaline |
| pH >= 12 | Very alkaline |
