Solution
The correct option is D 6
(4) The explanation for the correct option:
- Acids are chemical substances that produce Hydrogen ions (H+) when dissolved in water. It turns blue litmus red.
- When the pH of the solution is less than 7, the solution is said to be acidic. When the pH of the solution is above 7, the solution is basic and when it is equal to 7, the solution is neutral.
- Since the solution is acidic, because the litmus turns blue to red, the pH of the solution is probably 6 (less than 7).
The explanation for the incorrect options:
(1) The solution with a pH of 8, which is greater than 7, is basic in nature.
(2) The solution with a pH of 10, which is greater than 7, is basic in nature.
(3) The solution with a pH of 12, which is greater than 7, is basic in nature.
Final Answer: Hence, option (4) is correct. The pH of the solution is probably 6.
