The electrochemical basis for the advice of not to heat their garage in the winter has to be described. Concept introduction: Electrolysis : The process in which electrical energy is used to cause a non-spontaneous chemical reaction to occur. An electrolytic cell is an apparatus for carrying out electrolysis. In a spontaneous reaction standard emf of a reaction is positive; if the value if negative then it is non-spontaneous and external energy (electrical energy) is applied to carry out that reaction. During electrolysis, cations are reduced at cathode and anions are oxidized at anode. And in aqueous solutions water itself may be oxidized and/or reduced depends on the nature of other species involved/ present.

Interpretation Introduction

Interpretation:

The electrochemical basis for the advice of not to heat their garage in the winter has to be described.

Concept introduction:

Electrolysis: The process in which electrical energy is used to cause a non-spontaneous chemical reaction to occur. An electrolytic cell is an apparatus for carrying out electrolysis.

In a spontaneous reaction standard emf of a reaction is positive; if the value if negative then it is non-spontaneous and external energy (electrical energy) is applied to carry out that reaction.

During electrolysis, cations are reduced at cathode and anions are oxidized at anode. And in aqueous solutions water itself may be oxidized and/or reduced depends on the nature of other species involved/ present.
