pH is a measure of how acidic or basic a substance is. It is determined by the concentration of hydrogen ions in a solution.
The pH of a substance can be calculated using the formula pH = -log[H+], where [H+] represents the concentration of hydrogen ions in moles per liter.
The pH scale is a scale that ranges from 0 to 14 and is used to measure the acidity or basicity of a substance. A pH of 7 is considered neutral, while values below 7 are acidic and values above 7 are basic.
The pH of a substance can be affected by the concentration of hydrogen ions, temperature, and the presence of other substances that can donate or accept hydrogen ions.
pH is an important concept in science because it can affect the properties and behavior of substances. It is also used in various experiments and processes, such as in the production of certain chemicals or in the maintenance of a healthy environment for living organisms.
