The pH scale measures the acidity or alkalinity of a solution. A pH value of 7 indicates a neutral solution. Values less than 7 indicate acidic solutions, with decreasing pH corresponding to increasing acidity. Values greater than 7 indicate alkaline (basic) solutions, with increasing pH corresponding to increasing alkalinity. A pH of zero represents a high concentration of hydrogen ions, characteristic of a very strong acidic solution.

– pH is defined as the negative logarithm of the hydrogen ion concentration ([H+]).
– pH < 7 is acidic, pH > 7 is alkaline, pH = 7 is neutral.
– A lower pH indicates higher acidity.

While the standard pH scale usually ranges from 0 to 14, highly concentrated strong acids can have negative pH values, and highly concentrated strong bases can have pH values greater than 14. A pH of 0 is within the range of very acidic solutions.
