Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

Question

**Using the data in this graph:**

a. What is the equivalence point?

b. What is the half-way point of the titration?

c. What is the pH at the half-way point?

d. What is the pKa?

e. What is Ka for the acid being used?

**Graph Description:**

The graph is a titration curve plotting pH against Volume Base (mL). The x-axis represents the volume of the base in milliliters, ranging from 0 to 50 mL. The y-axis represents the pH, ranging from 0 to 14.

Initially, the curve starts at a lower pH and rises gradually. There is a sharp increase in pH around the midpoint, indicating the equivalence point. After this sharp rise, the curve levels off, reaching a higher pH value at increased volumes of base.
