## Fluorinated organic compounds are used as herbicides, flame retardants, and fire-extinguishing agents, among other things. A reaction such as CH3SO2F + 3 HF → CF3SO2F + 3H2 is carried out electrochemically in liquid HF as the solvent.

a)

Interpretation Introduction

Interpretation:

The mass of each product in the given reaction has to be determined if electrolysis of CH3SO2F happens.

Concept introduction:

Voltaic cell or Galvanic cell:

The device to produce electricity by using chemical reactions. In these divces are redox chemical reactions are occured.

A voltaic cell converts chemical energy into electrical energy.

It consists of two half cells. Each half cell consists of a metal and a solution of a salt of metal. Two half cells are connected by salt bridge.

The chemical reaction in the half cell is an oxidation reduction (redox)reactions.

For example:

Cell diagram of voltaic or galvanic cell is as follows.

Salt bridge                        Cu(s)|Cu2+(aq)  ||  Ag+(aq)|Ag(s)____________     ___________                                       Half cell             Half cell

### Explanation of Solution

The given reaction is as follows.

CH3SO2F + 3HF  CF3SO2F + 3H2

Let’s calculate the mol of each component:

Mol of HF:

mol of HF = 3 (mol of CH3SO2F)=3(150 g98 g mol-1)=4.59 mol

Mass of HF =4.59 mol × 20 g mol-1=92 g

Mol of CF3SO2F:

Mol of CF3SO2F = mol of CH3SO2F=150 g98 mol-1=1
