To find the pOH of a solution, you can use the formula pOH = -log[OH⁻]. Given that [OH⁻] = 1.41 × 10⁻¹³, calculate the pOH: pOH = -log(1.41 × 10⁻¹³) ≈ 12.85. Therefore, the pOH of the solution is approximately 12.85.
To find the pOH of a solution, you can use the relationship between pH and pOH, which is given by the equation: pH + pOH = 14. If the pH of the solution is 6.2, then the pOH can be calculated as follows: pOH = 14 - pH = 14 - 6.2 = 7.8. Therefore, the pOH of the solution is 7.8.
To find the pOH of a solution, you can use the formula pOH = -log[OH⁻]. Given that the hydroxide ion concentration [OH⁻] is 9.0 × 10⁻⁷ M, the pOH can be calculated as follows: pOH = -log(9.0 × 10⁻⁷) ≈ 6.05. Thus, the pOH of the solution is approximately 6.05.
A pOH of 7.0 indicates a neutral solution, not a basic solution. In a basic solution, the pOH would be less than 7.0.
When a solution is basic, the pOH is always less than 7. This is because basic solutions have a higher concentration of hydroxide ions (OH⁻), which results in a lower pOH value. In contrast, a neutral solution has a pOH of 7, while acidic solutions have a pOH greater than 7. Therefore, the pOH of basic solutions reflects their higher alkalinity.
The pH and pOH are related to each other through the equation: pH + pOH = 14 If the pH of a solution is 3, we can find the pOH by rearranging the above equation: pOH = 14 - pH = 14 - 3 = 11 Therefore, the pOH of the solution is 11.
To find the pOH of a solution, you can use the formula pOH = -log[OH⁻]. Given that [OH⁻] = 1.41 × 10⁻¹³, calculate the pOH: pOH = -log(1.41 × 10⁻¹³) ≈ 12.85. Therefore, the pOH of the solution is approximately 12.85.

The pOH is 6,4.
The pOH of a solution can be calculated using the formula: pOH = 14 - pH. For a solution with a pH of 6.2, the pOH would be 14 - 6.2 = 7.8.
The pOH of a solution can be calculated using the formula pOH = 14 - pH. Therefore, if the pH of a solution is 12.2, the pOH would be 14 - 12.2 = 1.8.
