The text from the image appears to be a set of questions related to acid and pH, likely from a chemistry assignment or test:a. Is the acid strong or weak? Explain.b. If 10.0 mL of acid was used, what is the concentration of the acid?c. The half-equivalence point turns out to be the acid’s pKa. Estimate the pKa from the graph and identify the acid.There are no graphs or diagrams visible in the image. ### Titration of an Unknown Acid with a Strong BaseThis document examines the pH titration of an unknown acid using a strong base, specifically 0.1 M NaOH. The graph below illustrates the change in pH as the volume of NaOH added increases.#### Graph Explanation- **Axes**: - The x-axis represents the volume of 0.100 M NaOH added, measured in milliliters (mL), ranging from 0 to 50 mL. - The y-axis displays the pH level, ranging from 0 to 14.- **Curve Description**: - Initially, the pH is low, indicating an acidic solution. - As the NaOH is added, the pH levels start to rise gradually. - Around the 25 mL mark, a sharp increase in pH is observed, indicating the equivalence point where the amount of acid equals the amount of base added. - After the equivalence point, the pH levels off, as further addition of NaOH has less effect on pH.- **Equivalence Point**: - The equivalence point occurs at a pH of 8.72. This is highlighted on the graph, showing the volume of NaOH that neutralizes the acid completely.This titration curve aids in identifying the properties of the unknown acid and understanding its behavior during the neutralization process.
