WebbThere 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. WebbPrior to collecting pH readings, the pH meter was calibrated using 2-point standard buffers (pH 4.0 and 7.0). Duplicate packages from each treatment were opened and using a pH electrode attached to a pH meter (Model HI199163, Hanna Instruments, Woonsocket, RI, USA) was inserted into the ground pet food.
