Chapter 14.7, Problem 12TY
Interpretation Introduction

Interpretation:

The formal potential of the given reaction has to be calculated.

O2+4H++4e-2H2O

Concept Introduction:

Cell Voltage:

Cell voltage is the difference between cathode potential and anode potential.

Ecell=E+-E-

Nernst equation:

In electrochemistry, the standard reduction potentials are related with the temperature and gas constant and standard electrode potentials and concentrations.

Ecell=E0cell-RTnFlog[cathode]n[anode]n

For Diprotic system the formal concentration is given by,

[H2A]=[H+]2F[H+]2+[H+]K1+K1K2

Where,

K1,K2 are acid dissociation constants for H2A

What would be the best choices for the missing reagents 1 and 3 in this synthesis? 1. PPh3 3 2. n-BuLi • Draw the missing reagents in the drawing area below. You can draw them in any arrangement you like. • Do not draw the missing reagent 2. If you draw 1 correctly, we'll know what it is. • Note: if one of your reagents needs to contain a halogen, use bromine. Click and drag to start drawing a structure.
Identify the missing organic reactants in the following reaction: X + Y H+ two steps Note: This chemical equation only focuses on the important organic molecules in the reaction. Additional inorganic or small-molecule reactants or products (like H2O) are not shown. In the drawing area below, draw the skeletal ("line") structures of the missing organic reactants X and Y. You may draw the structures in any arrangement that you like, so long as they aren't touching. Click and drag to start drawing a structure. Х :
