The absolute value of single electrode potential cannot be determined because the oxidation half reaction cannot take place without the reduction half. To overcome this difficulty the standard hydrogen electrode (SHE) is taken as the ..
Measurement of Electrode Potentials
Measurement of Electrode Potentials - The absolute value of a single electrode cannot be measured experimentally because a half-cell reaction cannot take place independently. One can measure only the difference between the electrode potentials of any two ..
Measurement of Electrode Potentials
The absolute value of a single electrode cannot be measured experimentally because a half-cell reaction cannot take place independently. One can measure only the difference between the electrode potentials of any two half-cell reactions. If th..
Single Electrode Potential
It is not possible to measure the absolute potential of a single electrode because neither the oxidation nor the reduction reaction can occur by itself. Also, we need two electrodes to measure the potential difference between two points. This difficulty can b..
Electrode Potential
>When neither the metal atom (M), nor the metal ion Mn+ undergo any change no charge is developed on the electrode relative to the solution. If the metal has relatively high tendency to get oxidized, its atoms will lose electrons readily and form Mn + ions, which go into the solution. The electrons..

A galvanic cell consists of two electrodes dipping into the same or two different electrolytes. No reaction takes place until a conducting wire joins the two electrodes. Once, a chemical reaction takes place at each electrode, electron transfer takes place. The electron-transfer..

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
This Tutor Vista is GREAT! loved this session, it helped me heaps.
This is very helpful and explains everything thoroughly. when asked to do problems slowly, tutors did them very thoroughly and even went extra mile to explain how and why with text - I just bow down to Turor Vista
Tutor Vista tutors are pleasant and great to work with, they were very patient and explained everything that is simple to follow. I love working with them. - John Coakley
