Question

Electrolytes conduct electricity due to the movement of:
A. electrodes
B. atoms
C. electrons
D. ions

Answer 1

Answer:

Ions because these are only present in the solution.

When electrodes are placed in an electrolyte and a voltage is applied, the electrolyte will conduct electricity. Lone electrons normally cannot pass through the electrolyte; instead, a chemical reaction occurs at the cathode, providing electrons to the electrolyte.

The dissolved electrolyte separates into cations and anions, which disperse uniformly through the solvent. Electrically, such a solution is neutral. If an electric potential is applied to such a solution, the cations of the solution are drawn to the electrode that has an abundance of electrons, while the anions are drawn to the electrode that has a deficit of electrons. The movement of anions and cations in opposite directions within the solution amounts to a current.

Answer 2

Electrolytes conduct electricity due to the movement of D. ions

Explanation:

• Electrolyte is water soluble salt of metal when electricity is passed through electrolyte, chemical decomposition of salt takes place.
• The salt undergoes ionisation and forms ions where they are free floating electric charges throughout the solution.
• There are two types of ions namely cations (positive ions) and anions (negative ions).
• The cation move towards cathode and anion move towards anode.
• Ions are formed in acids, salts and bases.
• This is effect is utilised in batteries and electroplating process.
