Ammonium chloride, NH4Cl, is used as an electrolyte in dry cells. Which of the following statements about a 0.10-M solution of NH4Cl is correct? Think about this: HCl is a strong acid, and hence, Cl– is a negligible base. On the other hand, is NH4+ a weak or negligible acid?
A. The solution is strongly basic.
B. The solution is weakly basic.
C. The solution is acidic.
D. Kb of NH3 = 1.8 × 10–5. Ka of NH4+ is, therefore, 5.6 × 10–10 which is less than one. A solution containing NH4+ and Cl– should be saturated in both ions at 0.10 M NH4Cl.
E. The solution is neutral.
