Question

Chapter 21, Problem 21.1P

Interpretation Introduction

Interpretation:

The definition for given terms oxidation and reduction has to be defined in terms of electron transfer and change in oxidation number.

Concept Introduction:

Oxidation: If electrons are moved from a species during a chemical reaction. The species whose electrons are removed is said to be oxidized.

Reduction: If electrons are gained to a species during a chemical reaction. The species which gets electrons are said to be reduced.

Redox reaction: It occurs when oxidation and reduction takes place at the same time in a chemical reaction.

Expert Solution & Answer

Explanation of Solution

The term oxidation is defined as loss of electrons from a compound and it is said to be oxidized. This results in increased oxidation number of that compound.

The term reduction is defined as gain of electrons by a compound and it is said to be reduced. This results in decreased oxidation number of that compound.

In oxidation-reduction reaction, transfer of electrons takes place from the oxidized substance to reduced substance. There will be increase in the oxidation number of oxidized compound in this reaction and decrease in the oxidation number of reduced compound of the oxidation-reduction reaction.

In the solid state, oxalic acid occurs as a dihydrate with the formula H2C2O4 C+2H2O. Use this formula to calculate the formula weight of oxalic acid. Use the calculated formula weight and the number of moles (0.00504mol) of oxalic acid in each titrated unknown sample recorded in Table 6.4 to calculate the number of grams of pure oxalic acid dihydrate contained in each titrated unknown sample.

1. Consider a pair of elements with 2p and 4p valence orbitals (e.g., N and Se). Draw their (2p and 4p AO's) radial probability plots, and sketch their angular profiles. Then, consider these orbitals from the two atoms forming a homonuclear л-bond. Which element would have a stronger bond, and why? (4 points)
