What does alkalinity of water indicates?
Alkalinity is a measure of water's ability to neutralize acids or resist changes that cause acidity, maintaining a stable pH.
Titration is used to measure the alkalinity of a water sample, and water with a pH of 8 or higher is considered alkaline.
Soils and geology have the biggest influence on water pH and alkalinity._{14 sept. 2022}
Why test drinking water for alkalinity?
Monitoring alkalinity in drinking water is important for both taste and for maintaining effective pH levels required for disinfection.
Moderate alkalinity is desirable in most water supplies.
Strong alkaline water has an unpleasant “soda” taste.
What is total alkalinity a measure of?
Total alkalinity is a measurement of the concentration of all alkaline substances dissolved in the water that can both attract and release Hydrogen ions (H⁺).
This interference with Hydrogen is why alkalinity buffers against change in pH.
Water alkalinity and pH are not the same.
Water pH measures the amount of hydrogen (acid ions) in the water, whereas water alkalinity is a measure of the carbonate and bicarbonate levels in water.
Think of carbonates and bicarbonates as dissolved limestone.

Alkalinity is a measure of the capacity of water to neutralize acids (see pH description). Alkaline compounds in the water such as bicarbonates (baking soda is one type), carbonates, and hydroxides remove H+ ions and lower the acidity of the water (which means increased pH).
