Just a few questions. I need to learn how to solve them.
1. The pH of a solution is 2.1, what is the [OH-]?
2. When [H+] = 4.28 x 10-10 M, what is pH and pOH?
3. The pOH of a solution is 11.5, what is the pH and [OH-]?
4. If the hydrogen ion concentration of a solution is 9.58 x 10-5 M, what is the pOH and hydroxide ion concentration?
5. The hydrogen ion concentration of a solution is 6.25 x 10-12 M, what is the hydroxide ion concentration, pH, and pOH?
The main thing I don't understand is the negative logarithm thing. Just an easy to understand explanation would be a life saver.
