Detailed explanation-1: -The correct answer is (b) 2. The pH scale is used to measure how acidic or basic a solution is.
Detailed explanation-2: -The pOH scale is similar to the pH scale in that a pOH of 7 is indicative of a neutral solution. A basic solution has a pOH less than 7, while an acidic solution has a pOH of greater than 7.
Detailed explanation-3: -A basic solution has a pOH of less than 7, while an acidic solution has a pOH of greater than 7. The pOH is convenient to use when finding the hydroxide ion concentration from a solution with a known pH.
Detailed explanation-4: -pOH is the measure of alkalinity, or hydroxide ion concentration, of a solution. If you know what the pH of the solution is, it gets easier to calculate its pOH value, as pH + pOH = 14. You could also apply the equation pOH =-log [OH-].
