Question

Standard reduction electrode potential of three metals abc are + 0.5 - 3 - 1.2 respectively the reducing power of these metals are

Answer 1

Answer:

If the activity of the hydrogen ion is 1 mol/l (pH=0) and hydrogen gas is bubbled into the solution so that partial pressure of hydrogen is 1 atm, the electrode potential is defined as zero volts at any temperature: E0=0.000 V.
