Define the ionic product of water and the concept of ph

 Ionic Product of Water and the Concept of pH:

• The ionic product of water, also known as the water dissociation constant (Kw), is a measure of the extent to which water dissociates into hydrogen ions (H+) and hydroxide ions (OH-). 
• The pH of a solution is a measure of the concentration of hydrogen ions in the solution, where a low pH indicates a high concentration of hydrogen ions, and a high pH indicates a low concentration of hydrogen ions.
