Question

If a buffer is prepared using 0.45 mol NH4+ and 0.55 mol NH3 in 1 liter of aqueous solution, is the buffering capacity of the solution great enough to maintain its pH if 25 g NaOH is added?

Select one:

a. Yes, the concentration of ammonia in the solution is great enough toneutralize the hydroxide.

b. Yes, the concentration of ammonium ions in the solution is great enough toneutralize the hydroxide.

c. No, the concentration of ammonia in the solution is not high enough toneutralize the hydroxide.

d. No, the concentration of ammonium ions in the solution is not high enough toneutralize the hydroxide.

e. No, a weak acid cannot neutralize a strong base.

Explanation / Answer

A) b. Yes, the concentration of ammonium ions in the solution is great enough to neutralize the hydroxide.
