I did this lab and this was the results of the lab
Initial buret volume: 50ml with added NaOH 0ml
final buret volume: 35.10 turned pink here
Total volume titrated to reach end-point: 14.90ml





What happened to the rise in pH as the end-point was approached?10.46
It jumped up dramastically.

then it asked this
Prepare a titration curve with pH on the y-axis and volume of base added on x-axis. Determine the equivalence point from the curve (steepest point of curve).

And I do not know what to do help please...
 
What it says.

Draw a graph. x-axis is the volume added. y-axis is the pH you found after adding x mL. As you rightly say, there is a dramatic rise at the equivalence point.

The equivalence point is where the graph is steepest.

That's all.
