Alkalinity (from Arabic: القلوية, romanized: al-qaly, lit. 'ashes of the saltwort') [1] is the capacity of water to resist acidification. [2] It should not be confused with basicity, which is an absolute measurement on the pH scale. Alkalinity is the strength of a buffer solution composed of weak acids and their conjugate bases.
The pH range is commonly given as zero to 14, but a pH value can be less than 0 for very concentrated strong acids or greater than 14 for very concentrated strong bases. [2] The pH scale is traceable to a set of standard solutions whose pH is established by international agreement. [3]
Wetland restoration projects have been shown to increase the resilience of freshwater systems to acidification and other environmental stressors. [20] Liming is one of the most common and best practices for remediating acidification. In this process calcium carbonate (CaCO 3) is added to the system to increase pH levels. [21]
Acid-neutralizing capacity or ANC in short is a measure for the overall buffering capacity against acidification of a solution, e.g. surface water or soil water.. ANC is defined as the difference between cations of strong bases and anions of strong acids (see below), or dynamically as the amount of acid needed to change the pH value from the sample's value to a chosen different value. [1]
Similarly, each unit increase in pH indicates a tenfold increase of the OH – concentration. In water with dissolved salts, the concentrations of the H 3 O + and the OH – ions may change, but their sum remains constant, namely 7 + 7 = 14. A pH of 7 therefore corresponds to a pOH of 7, and a pH of 9 with a pOH of 5.
Then, using the initial soil pH and the aluminium content, the amount of lime needed to raise the pH to a desired level can be calculated. [68] Amendments other than agricultural lime that can be used to increase the pH of soil include wood ash, industrial calcium oxide , magnesium oxide, basic slag (calcium silicate), and oyster shells.
Alkalinity is a factor that most often dictates the amount of boiler blowdown. High alkalinity promotes boiler foaming and carryover and causes high amounts of boiler blowoff. When alkalinity is the limiting factor affecting the amount of blowdown, a dealkalizer will increase the cycles of concentrations and reduce blowdown and operating costs.
Alkaline precipitation increases the pH of rainwater to 8.5-10, causing disturbances in aquatic ecosystems. These disturbances can cause physiological changes to aquatic life, changing the rates at which ammonia is dispelled, which leads to accumulation in organisms. [ 1 ]
