Webb11 apr. 2015 · So if with a strong monoacid you find $\mathrm{pH}=6.8$ with this formula the result is not correct and you have to make an other approximation or reasonning! Here we have $\mathrm{pH}=-0.69<6.5$ so you find a reasonable answer. And in water $\mathrm{pH}$ is between $0$ and $14$ so your solution is at $\mathrm{pH} \approx 0$ WebbWhy does tap water not have a pH of 7? It is important to keep mind that water (distilled, deionized, or tap) is NOT “pure” (i.e., pH equal to 7). The moment it comes in contact with air, CO 2 gas begins dissolving into it, forming carbonic acid. The actual pH, therefore, will typically be slightly less than 7.
