Why is Sodium Chloride(NaCl) a strong electrolyte substance?
Answers
Answer:
NaCl is an ionic compound. In water it dissolves completely forming ions. Since it dissolves completely forming Na^+ and Cl^- ions it is classified as a strong electrolyte.
Strong electrolytes are completely dissociated into ions in solution and conduct an electrical current strongly that is, they completely ionize in water and are good conductors of electricity. This means 100% of the dissolved chemical breaks into cations and anions. However, it does not mean the chemical completely dissolves in water!
Considering Sodium Chloride,
NaCl(s) = Na+(aq) + Cl-(aq)
Since, NaCl is an ionic solid (s), which consists of cations Na+ and anions Cl- . No molecules of NaCl are present in NaCl solid or NaCl solution. The ionization is said to be complete. The solute is one hundred percent (100%) ionized which makes it a strong electrolyte.
Weak electrolytes are only partly dissociated (examples are molecules like acetic acid which forms a weak electrolyte) as in they partially ionize in water.
Non electrolytes do not form ions at all and do not conduct electricity in their solutions.

Answer:
Sodium chloride dissolve in water to form ions that are Na+ and Cl- . Since it dissolve completely in water forming ions , it allows electricity to pass through them easily and thus it is an electrolyte.
