The conductivity of strong electrolyte

Correct answer: C. Decreases on dilution

  • A. Increases on dilution slightly
  • B. Does not change on dilution
  • C. Decreases on dilution
  • D. Depends on density of electrolyte itself

Explanation

When a strong electrolyte (a compound that completely dissociates into ions in solution) is diluted, the number of ions per unit volume decreases. This means that there are fewer charged particles available to carry the electric current, leading to a decrease in conductivity.Factors Affecting Conductivity Decrease:Decreased ion concentration: The main reason for the conductivity decrease. Fewer ions per unit volume translate to fewer charge carriers, lowering the ability to conduct electricity.Increased distance between ions: Dilution also increases the average distance between ions, hindering their mobility and reducing the efficiency of current flow.Interionic attractions: Although weaker at higher dilutions, these attractions can still exert some influence on ion mobility, especially in concentrated solutions.

About Transition Elements

Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
