Sodium hydroxide is a strong base and ammonium hydroxide is a weak base. Which of the following correctly portrays aqueous solutions of the two bases? Select one: A. NaOH(aq) and NH4+(aq) + OH-(aq) B. Na+(aq) + OH-(aq) and NH4OH(aq) C. Na+(aq) + OH-(aq) and NH4+(aq) + OH-(aq) D. NaOH(aq) and NH4OH(aq) E. none of the above
Homework Answers
Answer is B).
Since sodium hydroxide is a strong base it dissociate completely to give Na+ and OH- whereas ammonium hydroxide is a weak base thus it dissociate partially and remain as NH4OH.
