How to Use the Burette
In this burette-use worksheet, students are given directions for titration using a burette. They practice reaching the end point of titrations and calculate the mean volume of three trials.
Creative Chemistry
How to Use the Burette
In this burette activity, learners learn how to use a burette to perform a titration properly and run four trials, indicating their data. Students calculate the initial volume, the final volume, the titre volume, and the mean titre...
