Calculate the pH of a 1.00 L solution of 0.100 M NH₃(aq)after the addition of 0.010 mol HCl(g).For NH₃,pK_b = 4.74. A)10.21 B)9.26 C)8.31 D)11.46 E)7.00

Question

Quizplus · Accepted Answer

The correct answer is A because the pH of the solution will increase after the addition of HCl. The reaction between NH3 and HCl will produce NH4+ and Cl- ions, which will decrease the concentration of NH3 and increase the concentration of H+ ions. This will result in a higher pH.
