✔ 最佳答案
a)
NaOH(aq) is a strong electrolytes.
This is because NaOH "completely" dissociates in water to give mobile ions (Na⁺ and OH⁻) which conduct electricity.
NaOH(aq) → Na⁺(aq) + OH⁻(aq)
b)
HCl(aq) is a strong electrolytes.
This is because HCl "completely" ionizes in water to give mobile ions (Cl⁻ and H₃O⁺/H⁺) which conduct electricity.
2HCl(aq) → H₃O⁺(aq) + Cl⁻(aq)
OR: HCl(aq) → H⁺(aq) + Cl⁻(aq)
c)
C₆H₁₂O₆(aq) is a non-electrolyte.
This is because C₆H₁₂O₆ entirely exists as molecules in aqueous solution, and there are no ions to conduct electricity.
d)
NH₃(aq) is a weak electrolytes.
This is because NH₃ "partially" dissociates in water to give mobile ions (NH₄⁺ and OH⁻) which conduct electricity.
NH₃(aq) + H₂O(l) ⇌ NH₄⁺(aq) and OH⁻(aq)
e)
Ethanol (C₂H₅OH(aq)) is a non-electrolyte.
This is because ethanol entirely exists as molecules in aqueous solution, and there are no ions to conduct electricity.
