7th edition 6O.3
Posted: Sat Mar 09, 2019 11:22 am
In 6O.3, it asks to compare various aqueous ion solution to water at pH=7 to see which species will be reduced at the cathode. The answer key uses E=-0.42V for the reduction potential of water. However, in the appendix, the standard reduction potential of water is -0.83V. Can someone explain how they found the other value for pH=7??
