Ph of produced water
WebJan 30, 2024 · In a sample of pure water, the hydronium concentration is \(1 \times 10^{-7}\) moles per liter (0.0000001 M) at room temperature. The equation to find the pH of a solution using its hydronium concentration is: \[pH = -\log {(H_3O^+)}\] Using this equation, we find the pH of pure water to be 7. This is considered to be neutral on the pH scale. WebRT @AsiyaRodrigo: One reason why I don’t use cosmetics produced in Nigeria. The water and other substances added are contaminated.
