Question

The pOH of a solution is 3.1. Which of the following is true about the solution? It is acidic and has a pH of 10.9. It is basic and has a pH of 10.9. It is acidic and has a pH of 6.2. It is basic and has a pH of 6.2.

Answer 1

The pOH of a solution is 3.1. The solution is acidic and does not have a pH of 10.9.

Step-by-step explanation:

The pOH of a solution is 3.1. According to the information provided, in a neutral solution, the pH and pOH values are equal and both are 6.31. In acidic solutions, the pH is less than 6.31 and the pOH is greater than 6.31. In basic solutions, the pH is greater than 6.31 and the pOH is less than 6.31.

Since the pOH of the solution in question is 3.1, which is less than 6.31, it falls into the category of an acidic solution. Therefore, the solution is acidic and does not have a pH of 10.9.
