Where would you identify the equivalence points on this graph? 

The image is a line graph titled "pH vs mL base added," which illustrates the change in pH as different volumes of NaOH (sodium hydroxide) are added. **Axes:** - The x-axis represents the volume of NaOH added, measured in milliliters (mL), ranging from 0 to 60 mL. - The y-axis represents the pH level, ranging from 0 to 10. **Data Points:** - A series of blue dots indicate the actual pH levels measured at various volumes of NaOH added. **Trend Line:** - A linear trend line is fitted to the data points, depicted in blue. The equation of the line is \( y = 0.1566x + 0.481 \), where \( y \) is the pH and \( x \) is the mL of NaOH added. - The \( R^2 \) value is 0.9754, indicating a strong correlation between the volume of NaOH added and the resulting pH change. **Interpretation:** - As more NaOH is added, the pH increases, illustrating the basic nature of NaOH as it neutralizes acidic components, moving the solution toward higher pH values.
