The pH scale, which measures from 0 to 14, provides an indication of just how acidic or basic a substance is. Most parts of our body (excluding things like stomach acid) measure around 7.2 and 7.6 on the pH scale (a 7 is neutral on the scale). If foreign strong substances dramatically change this pH, our ...

WebOilfield waters typically have pH's from about 5.0 to 8.0. Some waters such as in CO2floods can have pH’s in the range of 4.0. PH can be measured with: an instrument pH tests strips or it can be calculated from CO2concentrations Hydrogen Sulfide (H2S) Hydrogen sulfide is a hazardous gas that occurs in some oilfield waters. Water (H2O) reversibly dissociates into hydrogen ions and hydroxide ions, which is described by the equilibrium constant for this chemical reaction, Keq (H2O) or simply Kw. The acidity or hydrogen ion activity of aqueous solutions controls many of its properties and is commonly expressed as the pH. ....................(5) … See more The resistivity of formation water is a measure of the resistance offered by the water to electrical current.

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. http://aqwatec.mines.edu/produced_water/intro/pw/
