How does pH relate to pOH?
The pH of a solution can be related to the pOH.
Consider a solution with a pH =4.0.
A basic solution has a pOH less than 7, while an acidic solution has a pOH of greater than 7.
The pOH is convenient to use when finding the hydroxide ion concentration from a solution with a known pH..
What is pOH formula?
To calculate the pOH of a solution you need to know the concentration of the hydroxide ion in moles per liter (molarity). The pOH is then calculated using the expression: pOH = – log [OH-] Example: What is the pOH of a solution that has a hydroxide ion concentration of 4.82 x 10-5 M?
How do you find pOH from pH?
To find the pOH, simply subtract the pH from 14. In order to calculate the pOH, take the negative log of the hydroxide ion concentration. To find the pH, simply subtract pOH from 14.
What does the pH of 7 indicate?
pH is a measure of how acidic/basic water is. The range goes from 0 – 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
