Question

In a galvanic cell, electrons flow from the ________ to the _______ . salt bride, anode anode, salt bridge cathode, anode salt bridge, cathode anode, cathode Which of the following transformations could not take place at the cathode of an electrochemical cell? NO Rightarrow N03- C02 Rightarrow C2042- V02+ Rightarrow V02+ H2AS04 Rightarrow H3AS03 O2 Rightarrow H2O2 The two electrodes Cr(s)/Cr3+(aq) and Fe(s)/Fe2+(aq) are combined to afford a spontaneous electrochemical reaction. The standard reduction potentials in V for Cr3+(aq) and Fe2+(aq) are -0.74 and -0.44. respectively. E Degree for the cell (in V) is +0.30 -0.88 +0.60 -0.60 +2.50

Explanation / Answer

7) anode to cathode

Remember that reduction, the gain of electrons, occurs at the cathode and oxidation, the loss of electrons, occurs at the anode. Thus, the flow is from the anode to the cathode, where they are consumed in reduction.
