So our PH is right in the middle. Remember, this represents acidity, and this represents how basic something is. Now, a PH of less than seven represents something that's acidic. And that's because as our PH decreases, our concentration of H ions increases. Because, look, as we go from seven to four, we go from ten to negative seven to ten to negative four Molar amounts of H plus in the same way that a PH of seven is basic. And that's because as we go down or as we go up on the PH scale, we go down, we decrease on the Molar scale.
