The hydrogen ion concentration of a solution is indicated by its <u>pH </u>value.
Explanation:
A measure of acidity or alkalinity of water soluble substances (pH stands for 'potential of Hydrogen'). A pH value is a number from 1 to 14, with 7 as the middle point.
Under normal circumstances this means that the concentration of hydrogen ions in acidic solution can be taken to be equal to the concentration of the acid.
The pH is then equal to minus the logarithm of the concentration value.
Values below 7 indicate acidity which increases as the number decreases, 1 being the most acidic.
The pH of a solution is a measure of hydrogen ion concentration, which in turn is a measure of its acidity.
Pure water dissociates slightly into equal concentrations of hydrogen and hydroxyl (OH−) ions. For a neutral solution, [H+] is 10−7, or pH = 7.
Mid-ocean ridges are found in the sea floor at divergent boundaries because both plates are moving away from each other creating the opening for the lava to sleep up. Mid-ocean ridges are where sea floor spreading occur by lava seeping up to the surface of the opening and cooling therefore forming new ground and pushing older layers of ground further away.
