A scale that measures the concentration of hydrogen ions in an aqueous solution.

Explanation:

pH is a logarthmic scale that is used to measure the concentration of hydrogen ions in an aqueous solution. It is used towards identifying how "acidic" or "basic" a solution is.

Acids are solutions with a low pH -> having a pH of less than 7.
Bass are solutions with a high pH -> having a pH of higher than 7.
There are also neutral solutions with a pH of 7.

I'm not explaining acids and bases so I won't talk about them that much.

pH can be calculated by using the formula: pH=-log[H^+]. Where:
=> pH is the pH. Simple as that. No units - pH is not a unit.
=> log is the logarithm... because pH is a logarthmic scale.
=> H^+ the concentration of hydrogen ions.

There are also things called pH indicators, that when reacting with a solution, will change a certain colour. Helpful to determine how acidic/basic an acid/base is.

I think that's the gist of it.

Hope this helps :)
