Ph of h3o+
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. WebJun 14, 2024 · Knowing the dependence of p H on [ H 3 O +], we can summarize as follows: If pH < 7, then the solution is acidic. If pH = 7, then the solution is neutral. If pH > 7, then the solution is basic. This is known as the p H scale. The pH scale is the range of value s from 0 to 14 that describes the acidity or basicity of a solution.
