Kara wants to find out how much alcohol is in a mixture of water and alcohol, she she designs an experiment to find out. Kara knows that alcohol vaporizes and becomes a gas at a lower temperature than water, so she plans to heat the mixture of water and alcohol so that the alcohol wil vaporize first. What data will Kara need to collect during the experiment in order to find out how much alcohol was in the original mixture?

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
