A voltaic cell is constructed using the SHE as one electrode and an unknown metal strip dipped into a 1 M aqueous solution in which its ions are soluble as the other electrode, with all other cell parts in place, including a KOH paste salt bridge. Write down the convincing evidence indicating that the SHE is behaving as the cathode in this voltaic cell.

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.

the awnser is group 12
