The pH of acids, bases and amphoterics in a solution

Translated by Google. Click to view original.
pH (potential of hydrogen) is a physical quantity which allows us to measure the acidity or basicity of a solution.
--if the pH<7 the solution is acidic (more H+ ions)
--if the pH=7 the solution is neutral (H+=HO-)
--if pH>7 basic solution (more HO- ion)
