it is the steepest part of the curve where the pH rises the fastest scores you brownie points with the instructors. pick your method (either will work)... The point on the titration curve at which all of the analyte has been neutralized is called the equivalence point, and on the graph it appears as an inflection point --- the steepest part of the entire curve, which is usually s-shaped. Once you find the equivalence point on your curve, you are ready to calculate.Difficulty:ModerateInstructions Things You'll Need Pencil Paper Calculator

**How to Plot a Titration Curve on Excel Techwalla.com**

I have to make a titration curve of adding 12 times 1 ml of acid to a buffer solution and doing this again by adding a base to the same buffer solution, with the measured pH-value on the vertical axis.... A typical titration curve obtained by plotting the measured pH of a weak acid solution as a strong base is added using graphical analysis for Windows is illustrated as follows: The equivalence point is halfway up the vertical portion of the curve, about 27 mL for this titration. The pH is about 9 at the equivalence point. 1. To obtain a better approximation of the volume at the equivalence

- Excel Tutorial for Making Titration Curves and Derivative Curves This tutorial will show you how to draw titration curves, and the first and second derivatives of curves using Excel (For Strong acid-strong base titration, Titration of a weak acid, Polyprotic systems, and Acid-base buffers labs) Note: You should use your data that you collected
- The equivalence point is an important feature of a titration curve because it allows us to determine the concentration of an unknown acid or base. At the equivalence point, the
- point, read the first derivative curve from the volume of base added (16.50 mL in the graphed example, above) up to where that point intersects the "S" shaped curve (called a SIGMOID curve), then read to the left on the pH axis (7.21 in the graphed example, above).
