There is an important inverse relationship between pH and pOH in that pOH values greater than 7 define solutions that are acidic! This is the result of the sum: pH + pOH = 14. Using this expression, one can determine the pOH if the pH is known. A solution at pH 5.5 would thus have a pOH of 8.5.A student dissolves 13.4 g of potassium chloride (KC1)in 300. g...
