Question

which of the following is an example of a weak electrolyte? * sugar (c₁₂h₂₂o₁₁) hydrochloric acid (hcl) ammonia (nh₃) sodium chloride (nacl)

Explanation:

• Sugar (\(C_{12}H_{22}O_{11}\)) is a non - electrolyte as it does not dissociate into ions in solution.
• Hydrochloric acid (\(HCl\)) is a strong electrolyte as it completely dissociates into \(H^{+}\) and \(Cl^{-}\) ions in solution (\(HCl

ightarrow H^{+}+Cl^{-}\)).

• Ammonia (\(NH_{3}\)) is a weak electrolyte. In water, it undergoes a partial ionization: \(NH_{3}+H_{2}O

ightleftharpoons NH_{4}^{+}+OH^{-}\).

• Sodium chloride (\(NaCl\)) is a strong electrolyte. It completely dissociates into \(Na^{+}\) and \(Cl^{-}\) ions in solution (\(NaCl

ightarrow Na^{+}+Cl^{-}\)).

Answer:

Ammonia (\(NH_{3}\))
