Combining these two half reactions requires writing the zinc ion to zinc metal half reaction the reverse of the way it appears in the table of standard reduction potentials. When the direction of a half reaction is reversed, so that it can be added to another half reaction, the sign of its...

Daniell cell electrochemistry may be written as two half-reactions. corbac40 / Getty Images A half-cell is half of an electrolytic or voltaic cell, where either oxidation orreductionoccurs. The half-cellreactionat theanodeis oxidation, while the half-cellreactionat thecathodeisreduction. Half-Cell...
Balance the equation using half reactions: MnO_4^- + Zn(s) \rightarrow MnO_2(s) + Zn^{2+} (aq) in basic solution. Balance the following in basic solution. Sn(OH)2(s) + O2(g) to SnO2(s), Ti(s) + CrO42 (aq) to Ti(OH)3...
The role of the canonical catalytic triad (Ser-112, His-265, Asp-237) in mediating these two half-reactions remains unclear. We previously reported that the BphD-catalyzed hydrolysis of HOPDA (λmax is 434 nm for the free enolate) proceeds via an unidentified intermediate with a red-...
