Chapter 7, Problem 46Q

(a)

Interpretation Introduction

Interpretation:

Using the given data in the given combustion of hydrogen, which species is oxidized and which is reduced has to be determined and explained.

Concept introduction:

A galvanic cell is an electrochemical cell. Electrochemical cell is a device capable of converting chemical energy into electrical energy or induces chemical energy by electrical energy. In the galvanic cell spontaneous redox reaction takes place. Redox reaction means the reaction in which the oxidation state of the atoms changes due to the occurrence of both reduction and its complementary oxidation reactions. The element under oxidation reaction loses electron whereas the element in the reduction gains electron.

Oxidation: The gain of oxygen or the loss of hydrogen or the loss of an electron in a species during a redox reaction is called oxidation.

Reduction: The loss of oxygen or the gain of hydrogen or gain of an electron in a species during a redox reaction is called reduction.
