WebVideo transcript. - [Voiceover] pH is defined as the negative log base 10 of the concentration of hydronium ions. Let's say we want to find the pH of water. To find the pH of water, we would take the negative log of the concentration of hydronium ions. For water, at 25 degrees Celsius, the concentration is 1.0 times 10 to the negative seven molar. WebControlling pH vs. Containing pH. Rather than trying to control pH, instead, try to contain it. By its very nature, pH moves around when you do anything to the water, and it naturally rises over time too. Trying to control it is futile–especially trying to control it within tight parameters like 7.4 to 7.6.
