Alkalinity is not a chemical in water, but, rather, it is a property of water that is dependent on the presence of certain chemicals in the water, such as bicarbonates, carbonates, and hydroxides. A definition of alkalinity would then be "the buffering capacity of a water body; a measure of the ability of the water ...

WebJan 30, 2024 · pH and pOH. Because the constant of water, K w is \(1.0 \times 10^{-14}\) (at 25° C), the \(pK_w\) is 14, the constant of water determines the range of the pH scale. To understand what the pK w is, it is important to understand first what the "p" means in pOH and pH. The addition of the "p" reflects the negative of the logarithm, \(-\log\). Therefore, … WebAlkalinity or Acidity (pH) vs. Millivolts (mV) The term pH means Potential Hydrogen and thus this pH number corresponds also to a voltage measurement.
