Electrodes of Hydrogen reduction and oxygen reduction
« on: September 04, 2018, 03:14:39 PM »
My homework:
Find out potential of electrodes of Hydrogen reduction and Oxygen reduction in acidic as well as basic medium. What exactly should I search for?

It is a Forum Rule (see red link above) that you must show your work or provide your thoughts before we can help you.  Do you know what the key terms mean?  I would say that two of the key terms are "potential" and "reduction."

I didn't work on it since it was too vague to exactly understand the question. I just want to know what I should be looking for; like if I should write examples ?

I would not describe it as being vague.  What does the word "potential" mean to you in a chemical context?

Umm I guess the extent of ability to get oxidised/reduced? But what should I do about H and O?

I agree there is no way of giving an exact answer, only just some ballpark values. I would go for pH=1.0 and pH=13.0.

A thumbnail definition of a reduction potential is that it is a number that gives the propensity to gain a certain number of electrons.  It is a thermodynamic quantity.
