Chapter 16, Problem 16.136CP

Interpretation Introduction

To Determine:

Sketch the titration curve.

Calculation:

As, K_a = 10-4<< 1
HA is the weak acid whereas, NaOH is strong base.
For titration of weak acid vs strong base, the initial pH is higher in comparison to the pH of titration of strong acid vs strong base.

(b)

To Determine:

Concentration of base to get equivalence point of titration

Calculation:

M₁ V₁ = M₂ V₂

1. * 50 = 0.01 *V₂
V₂ = 50 mL
Thus, 50 mL of base required to neutralize acid and to reach equivalence.

(c)

To Determine:

pH of this titration

(c)

Interpretation Introduction

To Determine:

pH at half way of equivalence point
