Question

The pOH of several solution is given below. Determine pH of each solution and state whether the solution is acidic, basic, or neutral. A) pOH = 2.6 (1pt) B) pOH = 10.5 (1pt)

Answer 1

To determine the pH of each solution and classify them as acidic, basic, or neutral, we need to use the relationship between pH and pOH. The sum of pH and pOH is always equal to 14:

pH + pOH = 14

Let's calculate the pH for each given pOH value:

A) pOH = 2.6

To find the pH, we can subtract the given pOH from 14:

pH = 14 - 2.6

pH ≈ 11.4

Solution A has a pH of approximately 11.4. Since the pH is greater than 7, it is considered basic.

B) pOH = 10.5

Similarly, we can calculate the pH by subtracting the given pOH from 14:

pH = 14 - 10.5

pH ≈ 3.5

Solution B has a pH of approximately 3.5. Since the pH is less than 7, it is considered acidic.
