Webb12 juni 2024 · A fundamental equation to know regarding pH is that (near 25oC ), pH+pOH = 14.00. That is, near 25oC, the sum of the pH and pOH is always 14.00. Therefore, pOH = 14.00 − pH = 14.00 − 7.0 = 7.0. Since the pH and pOH are equal, this solution is said to be neutral; i.e. it is neither acidic nor alkaline (basic). Answer link. Webb1.031.
