Using the graph, identify the half way and equivalence point. Base: NaOH Acid: unknown 11
The image displays a graph titled "pH vs NaOH (mL)," which represents the titration curve of an acid-base reaction. **Axes:** - The x-axis is labeled "Volume of base added (mL)" and ranges from 0 to 45 mL. - The y-axis is labeled "pH" and ranges from 0 to 10. **Data Description:** - The graph shows data points plotted as blue dots. - Initially, from 0 to approximately 19 mL of NaOH, the pH remains relatively constant, around 4. - Between 19 mL and 30 mL of NaOH added, the pH decreases sharply, indicating the equivalence point or the point at which the amount of acid equals the amount of base added. - After 30 mL, the pH levels off again, approaching a pH of around 2, indicating an excess of acid. This graph exemplifies a typical titration curve involving the gradual addition of a base (NaOH) to an acid, with the pH change monitored throughout the process. The sharp inflection point on the graph is crucial for determining the equivalence point in titration experiments.
