Question

$NaCl$ shows Schottky defects and $AgCl$ Frenkel defects. Their electrical conductivity is due to ________.

• A. motion of ions and not the motion of electrons
• B. notion of electrons and not the motion of ions
• C. lower coordination number of $NaCl$
• D. higher coordination number of $AgCl$

Answer 1

Answer: (A)

motion of ions and not the motion of electrons

$NaCl$ shows Schottky defects Whereas $AgCl$ shows frenkel defects. Their electrical conductivity is due to the motion of ions and not the motion of electrons because both the compounds are ionic compounds. The electrical conductivity of ionic compounds is due to the movement of ions.

Hence option $A$ is correct.
