Welcome to the NCERT Solutions for Class 12 Chemistry - Chapter The Solid State. This page offers a step-by-step solution to the specific question from Exercise 1, Question 8:
Ionic solids conduct electricity in molten state but not in solid state. Explain.
. With detailed answers and explanations for each chapter, students can strengthen their understanding and prepare confidently for exams. Ideal for CBSE and other board students, this resource will simplify your study experience.Ionic solids conduct electricity in molten state but not in solid state. Explain.
In an ionic solids the lattice is made of positive and negative ions. These are held together by ionic bonds-the strong electrostatic attractions between oppositely charged ions. Consequently, the cations and anions attract each other and pack together in an arrangement so that the attractive forces maximize. The ionic solids are insulators in the solid state because the ions are entrapped in fixed places in the crystal lattice and cannot move when electric field is applied. However, in molten state, they become good conductors of electricity. This is due to the fact that in molten state, the well- ordered arrangement of ions in the solids is destroyed and the ions are in a position to move about in the liquid medium when an electric field is applied. For example NaCl.
The reaction between A and B is first order with respect to A and zero order with respect to B. Fill in the blanks in the following table:
| Experiment |
A/ mol L - 1 |
B/ mol L - 1 |
Initial rate/mol L - 1 min - 1 |
| I | 0.1 | 0.1 |
2.0 × 10 - 2 |
| II | -- | 0.2 |
4.0 × 10 - 2 |
| III | 0.4 | 0.4 | -- |
| IV | -- | 0.2 |
2.0 × 10 - 2 |
