Step-by-step explanation:
The pH measures how acidic or basic an aqueous solutions is. If the pH of that solution is greater than 7 we say that is an acidic solution, if the pH is equal to 7 we say that it is a neutral solution and when the pH is lower than 7 it is a basic solution.
pH > 7 = acidic pH < 7 = basic pH = 7 = neutral
The pH can be calculated with this formula:
pH = - log [H+]
The pH is the negative logarithm ("log") of the hydrogen ion (H+) concentration of a solution.
Answer: The pH measures how acidic or basic an aqueous solutions is.
