WebVideo Transcript. normally pH has a range from 0 to 14 and is not negative. However, if you have a very concentrated acid, for example, um, then you can find that you have ah, negative pH, such as negative log with a concentration of two for hydrogen would give us a pH of negative 0.3. WebThat gives us pH plus 4.75 is equal to 14.00. And solving for the pH, we get that the pH is equal to 9.25. So we have the pH and our goal is to solve for the concentration of hydronium ions, and pH is equal to the negative log of the concentration of hydronium ions. So we can plug our pH right into this equation. WebMar 2, 2024 · You can see that acid rain can be very acidic, and it can affect the environment in a negative way. ...
