If the pH of solution is 1, its pOH will
Correct answer: A. 13
- A. 13
- B. 11
- C. 9
- D. None of the above
Explanation
The pOH of a solution can be calculated using the relationship: pH + pOH = 14. This equation holds true for aqueous solutions at 25°C. Given that the pH of the solution is 1, you can find the pOH by rearranging the equation to pOH = 14 - pH. Substituting the given pH value, pOH = 14 - 1 = 13. Therefore, the correct answer is Option A.Other options are incorrect because they do not satisfy the fundamental relationship between pH and pOH. Specifically, Option B suggests a pOH of 11, which would imply a pH of 3, and Option C suggests a pOH of 9, implying a pH of 5. Neither is consistent with the given pH of 1. Option D is incorrect as it asserts that none of the options is correct, which is false since Option A is correct.

About Acids, Bases and Salts
Acid and base behaviour is explained through the Bronsted-Lowry transfer of protons and the Lewis donation or acceptance of electron pairs. The topic includes pH, pOH, ionisation and water equilibrium, plus salt formation and hydrolysis, where a salt solution may become acidic, basic or neutral.
