1) Sodium chloride undergoes an electrolysis reaction producing two new substances. One is a metal and the other is a gaseous element.


a) Create a word equation

b) Create a skeleton equation

c) Balance each equation

Sagot :

Metallic sodium and chlorine gas are produced by the electrolysis of molten sodium chloride.

What is a word equation?

A word equation represents a chemical reaction using the names of the substances involved.

a) Word equation:

Sodium chloride + electrolysis →  Sodium hydroxide + Hydrogen gas, Chlorine gas

b) The following reactions take place during the electrolysis of brine solution :

NaCl =[tex]Na^+ +Cl^-[/tex]

[tex]H_2O[/tex] =[tex]H^+ +OH^-[/tex]

Now there are two cations and two anions which get discharged in the following way :

At cathode : [tex]2H^+ +2e^-[/tex] = [tex]H_2[/tex]

At anode: [tex]2Cl^- - 2e-[/tex]=[tex]Cl_2[/tex]

The remaining ions

[tex]Na^+ +OH-[/tex] = NaOH

That's why we get [tex]H_2[/tex], [tex]Cl_2[/tex] and NaOH.

c) Balance each equation is:

2NaCl (l)  →   2Na(s) + [tex]Cl_2[/tex](g)
