What does it mean for a solution to be acidic or basic (alkaline)?
pH Value | H+ Concentration Relative to Pure Water | Example |
---|---|---|
7 | 1 | pure water |
8 | 0.1 | sea water, eggs |
9 | 0.01 | baking soda |
10 | 0.001 | Great Salt Lake, milk of magnesia |
Simply so, what has a pH of 7?
A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic.
Also to know is, what is the pOH of a solution that has a pH of 7?
The pOH scale is similar to the pH scale in that a pOH of 7 is indicative of a neutral solution. A basic solution has a pOH of 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.
pH is a measure of the amount of Hydrogen ions (H+) in a solution. Even in pure water ions tend to form due to random processes (producing some H+ and OH- ions). The amount of H+ that is made in pure water is about equal to a pH of 7. That's why 7 is neutral.
