A solution conducts electricity well, but the same substance in dry state does not. What is the most suitable reason?

Answer and explanation

Correct answer: Mobile ions are available in aqueous state

Electrical conduction in an electrolyte occurs through the movement of charged particles. When many acids, bases, or salts dissolve in water, they separate into mobile positive and negative ions, which carry current through the solution. In the dry solid, these ions are generally fixed in a lattice and cannot move freely. Therefore, option A is correct; the other choices confuse conductivity with electron speed, colour, or metallic conversion.
