Question

I need help on finding the equivalence point volume and the pH at the half way point? 

2) Find the equivalence point volume for both of the "good" trials. This will be most obvious using your table and the graph from either the first or second derivative, ideally the second derivative plot. You may need to zoom in on your plot to determine the volume at that point. Do not simply use a piece of your data, instead make a visual estimate of where this would occur. This may require you to add in extra gridlines! Since you will have done this visually in Excel, you may simply write your answers here. Equivalence point volume for your best trial Type your value and units here! 3) Determine the pH at the half-way point (half-way in terms of volume) for CHEM& 162: Lab 6 - pH Titration: Post-lab Report Page 2 of 4 each of the two good trials. Do this by using the equivalence point volume and the pH vs volume added plot separately for each of the trials. You may need to zoom in on your plot to do this. This should not be directly from one of your data points, it should be based on the trend of your plot. You may "connect the dots" for this part, as it will be easiest to estimate the pH at the half-equivalence point. This may require you to add in extra gridlines! Since you will have done this visually in Excel, you may simply write your answers here. pH at half-equivalence point for your best trial Type your value here!
