Solution

The correct option is B <7

The pOH scale is similar to the pH scale. Solution with pOH of 7 is the indicative of a neutral solution at 25 oC So , when the value of pOH is greater than 7 , then it will come into acidic range and when the pOH is less than 7 , then the solution will come in basic range.
As here the solution is basic So , its pOH should be <7.
