pH is a measure of the hydrogen ion activity in a solution. Pure water that contains an equal balance of positive hydrogen ions (H +) and negative hydroxide ions (OH -) has a neutral pH.
● Solutions with a higher concentration of hydrogen ions (H +) than pure water are acidic and have a pH less than 7.
● Solutions with a higher concentration of hydroxide ions (OH -) than water are basic (alkaline) and have a pH greater than 7.
PH measurement is a key step in many water testing and purification processes:
● A change in the pH level of water can alter the behavior of chemicals in the water.
● pH affects product quality and consumer safety. Changes in pH can alter flavor, color, shelf-life, product stability and acidity.
● Inadequate pH of tap water can cause corrosion in the distribution system and can allow harmful heavy metals to leach out.
● Managing industrial water pH environments helps prevent corrosion and damage to equipment.
● In natural environments, pH can affect plants and animals.
