In the Neutralization of 50

question 88

Multiple Choice

In the neutralization of 50.0 mL of 0.1 M BOH (a weak base with Kb = 1.6 × 10^-7) with 0.10 M H₂SO₄, the most correct description of the solution at the mid-point of the titration, i.e., half neutralized, is:

• A) a solution in which [B⁺] essentially equals [BOH]
• B) a solution in which [B⁺] essentially equals 4 × 10^-4 M
• C) a solution whose volume is 75 mL and contains some undissociated BOH molecules and some B⁺, OH^-, and HSO₄^- ions
• D) a solution containing SO₄^2- and B²⁺ ions
• E) a solution in contact with BSO₄ solid
