Answer: option c) the strongest base in aqueous solution is NaOH
Step-by-step explanation:
the strongest base in aqueous solution is NaOH because strength of a base is determined by its ability to donate hydroxide ions (OH-) in solution. and NaOH dissociates completely in water to produce Na+ and OH- ions. The presence of a fully dissociated hydroxide ion makes NaOH a strong base.
While, HOC2H4OH and CH3OH are weak acids. HOC2H4OH is ethylene glycol and CH3OH is methanol are weak acid due to the presence of the (-OH) group.
Also, NH3 (ammonia), is a weak base though it can accept H⁺ to form NH4+
