A 0.1 M aqueous solution of __________ will have a pH of 7.0 at 25.0°C. NaOCl KCl NH₄Cl Ca(OAc)₂

Question

Quizplus · Accepted Answer

KCl is a salt of a strong acid (HCl) and a strong base (KOH) and therefore does not undergo hydrolysis. As a result, it will not affect the pH of the solution, which will remain at 7.0. The other choices, NaOCl, NH₄Cl, and Ca(OAc)₂, are all either weak acids or weak bases, and their presence in solution will affect the pH. The choice E, which includes both KCl and NH₄Cl, is incorrect because NH₄Cl is also a weak base and will affect the pH of the solution, leading to a pH different from 7.0.
