The video explores whether sucrose (C12H22O11) is an electrolyte. It explains that for a substance to be an electrolyte, it must dissolve in water and produce ions, allowing the solution to conduct electricity. Sucrose dissolves in water but does not dissociate into ions, thus it is a non-electrolyte. The video also examines the elemental composition of sucrose, noting that it consists of non-metals like carbon, hydrogen, and oxygen, which form molecular compounds that are typically non-electrolytes, except for acids. The conclusion reaffirms that sucrose is a non-electrolyte.

What is the primary reason sucrose is considered a non-electrolyte?

• It conducts electricity when dissolved.

• It is made of metal elements.

• It does not produce ions when dissolved.

• It does not dissolve in water.

What must a substance do to be classified as an electrolyte?

• Dissolve in water and produce ions.

• Remain solid in water.

• Be composed of metal elements.

• Conduct heat when dissolved.
