High reduction potential
Solids, gases, and liquids are identified; all other species are aqueous. Reduction reactions in acidic solution are written using H + in place of H 3 O +. You may rewrite a reaction by replacing H + with H 3 O + and adding to the opposite side of the reaction one molecule of H 2 O per H +; thus.

Redox potential is a measure of the ease with which a molecule will accept electrons, which means that the more positive the redox potential, the more readily a molecule is reduced. … 2.18 Matching Redox Potentials of Inorganic and Organic Chemicals. ReactionFrom the definition of reduction potential, we can conclude that the reduction potential more will be the affinity towards electrons, more the possibilities to get reduced. From the above points, more the reduction potential value stronger the oxidizing agent. Hence, the strong oxidizing agent has a high value of reduction potential.An example would be ½ O2/H2O, where H2O could serve as an electron donor and O2 could serve as an electron acceptor. Each half reaction is given a standard reduction potential (E’0) in volts or millivolts, which is a measurement of the tendency of the donor in the reaction to give up electrons. A substance with greater tendency to donate ... Buying a new computer is a great opportunity to do some exploration in search of the best tech.
