For NaCl , the number of Schottky pairs per cm ^3 at room temperature is

Options

  1. A10¹²
  2. B10²³
  3. C10⁶
  4. D10⁴

Correct answer

C. 10⁶

Step-by-step solution

For 1 ~cm ^3 of NaCl , there are 10²² ions, so there are 10¹⁶ ions present per Schottky defect. Therefore, for each cm ^3 , there are 10^6 Schottky pairs at room temperature.
