Question

If the enthalpy of formation of HCl and CL- are -92.3kj/mole and -167.44kj/mol, find the enthalpy of solution of chlorine gas

Answer 1

Plz go through the following attatchment carefully

Answer 2

HCl can exists in two forms. It is either in aqueous or in gaseous form. It can be formed from Hydrogen and chlorine ions or gasses.

Hydrogen Chloride aqueous delta H f = -92.30

Hydrogen Chloride gaseous delta H f = -167.2



examples of production of HCl

Aqueous HCl can be produced in our stomach from Carbon dioxide and Water as starting material.

CO2 + H2O ---> H2CO3

carbonic acid produces proton

H2CO3 <---> H+ + HCO3-

That can combine with the freely floating Cl- ion in the cell thus producing HCl.



Gaseous HCl can be produced via burner process. This is an exothermic reaction.

H2 (gas) + Cl2 (gas) --> HCl (gas)
