Distilled Water and Electrolyte Classification

The video explores whether distilled water is an electrolyte or a non-electrolyte. It defines an electrolyte as a substance that dissolves in water to produce ions, allowing the solution to conduct electricity. Although distilled water does not dissolve in itself, it undergoes auto ionization, producing a small number of ions. This process suggests that distilled water could be considered a weak electrolyte. The video concludes by presenting both perspectives: distilled water does not meet the strict definition of an electrolyte, but due to auto ionization, it can be seen as a weak electrolyte.

What is the main question addressed in the video regarding distilled water?

• Whether distilled water is safe to drink

• Whether distilled water is an electrolyte or a non-electrolyte

• The cost of producing distilled water

• The chemical formula of distilled water

What is the definition of an electrolyte?

• A substance that is insoluble in water

• A substance that changes color in water

• A substance that evaporates quickly

• A substance that dissolves in water and produces ions

Why does distilled water not fully meet the definition of an electrolyte?

• It is not pure

• It does not conduct electricity

• It does not produce ions

• It does not dissolve in water

What is auto-ionization in the context of water?

• The process of water molecules evaporating

• The process of water molecules breaking apart into ions

• The process of water molecules freezing

• The process of water molecules condensing

What ions are produced during the auto-ionization of water?

• H2 and O2

• Na+ and Cl-

• CO2 and H2O

• H3O+ and OH-

What does the equilibrium state in water indicate?

• Water molecules are stable and unchanging

• Water molecules are both breaking apart and coming together

• Water molecules are only coming together

• Water molecules are only breaking apart

Why can distilled water be considered a weak electrolyte?

• It does not contain any ions

• It is highly conductive

• It has a high concentration of ions

• It has a low concentration of ions

What is the final conclusion about distilled water's classification?

• It is a weak electrolyte

• It is a non-electrolyte

• It is a strong electrolyte

• It is not an electrolyte at all

What argument supports the classification of distilled water as a weak electrolyte?

• The purity of the water

• The high cost of production

• The absence of ions

• The presence of auto-ionization
