Answer: The correct answer is Option B.
Step-by-step explanation:
pH is defined as the negative logarithm of hydrogen ion concentration. It is also defined as the power of hydrogen ions that are present in a solution. It ranges to the scale of 1 - 14.
On the basis of this scale, the solutions are divided into 3 categories, which are:
- If the pH of the solution lies in the range of 1 to 6.9, the solution is said to be acidic.
- If the pH of the solution lies in the range of 7.1 to 14, the solution is said to be basic.
- If the pH of the solution is exactly 7, the solution is said to be a neutral solution.
From the above information, we conclude that the water sample having pH = 6.0 is acidic in nature.
Hence, the correct answer is Option B.
