| Make up the equations of electrode processes (inert anode) and the molecular equation of the reaction taking place during the electrolysis of a melt or electrolyte solution, a NaF melt.
Melt:
NaF <=> Na + + F–;
K (-): Na + + 1e => Na0;
А (+): 2F– – 2e => F20;
2NaF = (electric current) => 2Na + F2 ↑.
Solution:
NaF <=> Na + + F–;
К (-): 2H2O + 2e => H20 + 2OH–;
A (+): 2H2O – 4e => O20 + 4H +;
2H2O = (electric current) => 2H2 ↑ + O2 ↑.
