The hydrogen ion concentration refers to the amount of hydrogen ions (H+) present in a solution. It is measured in moles per liter (M) and indicates the acidity or basicity of the solution.
It is a measure of how acidic or basic a solution is and is calculated using the negative logarithm of the hydrogen ion concentration.
A solution with a high concentration of hydrogen ions, resulting in low pH values.
A solution with a low concentration of hydrogen ions, resulting in high pH values.
