Reduction Potential
If an electrode undergoes spontaneous reduction when coupled with a standard hydrogen electrode (SHE) it is said to have a positive value of reduction potential and vice ver..

Reduction of Ores
Reduction of Ores - The oxide obtained by calcination or roasting is then reduced by either carbon or hydrogen. Carbon is usually used in the form of coke, or carbon monoxide. Not all metallic oxides can be reduced by carbon or carbon monoxide. Thus, in order to extract metal from its ore..
Reduction properties
Due to their low ionization energies all group 2 elements tend to lose their valence electrons and act as strong reducing agents. The decrease of the reduction potential values down the group, indicate an increase of strength as a reducing agent. However the members of this gro..

When the whole iron has been oxidized, the supply of steam is stopped and stream of water gas (H 2 + CO) is passed to reduce Fe 3 O 4 to iron...Measurement of Electrode Potential
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 standard or referen..
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 be so..
Calculation of Cell Potential
Calculation of Cell Potential - In an electrochemical cell, electrons flow from negative electrode to the positive electrode. This shows that there is a potential difference between the two electrodes. The minimum potential which causes the flow of the electrons from t..

She should be the head of Tutor Vista. She knows how to treat her students. Her teaching style is spectacular.
Tutor was excellent, asnwered the question rapidly and provided the information I needed to understand the problem.
Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
Even though I don't feel good, the tutor helped me by totally helping me understand!
