pH activity refers to the measurement of acidity or alkalinity of a solution.

• pH activity is measured on a scale of 0-14, with 7 being neutral, below 7 being acidic, and above 7 being alkaline

• It is important in various fields such as chemistry, biology, and environmental science

• For example, pH activity is used to determine the acidity of soil for agriculture, the pH of water for aquatic life, and the pH of blood for med

The pH value decreases when acid is added and increases when alkali is added.

• Acids release hydrogen ions (H+) when dissolved in water, which increases the concentration of H+ ions and lowers the pH value.

• Alkalis release hydroxide ions (OH-) when dissolved in water, which decreases the concentration of H+ ions and raises the pH value.

• The pH scale ranges from 0 to 14, with 7 being neutral. Values below 7 are acidic, and ...read more
