One of the logs of log states that log of X times Y equals log x plus log y. The second part I want to look at is the formulas for PH and poh. PH is equal to negative log of the hydronium concentration, and Poh is equal to the negative log of the hydroxide concentration. Now, in Part C, remember, at 25 degrees Celsius, our Kw will always be 1.0
times 10th to negative 14. Now, if we want to take the PH of kw, which is PKW, we simply write PKW is equal to negative log of one times ten to the negative 14. Right?
