An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with their ...

This lab includes a demonstration of the proper use of a burette system for titrations; including a detailed description, instructional video, and opportunity for students to collect data to ...

I’m sure many of you reading this can remember your first acid-base titrations in chemistry class—the thrill of watching the pH indicator change color, and the fear of opening the stopper too much and ...

ACE OF BASE A paper-based device titrates basic solutions of NaOH. The numbers at the end of each spoke indicate the concentrations of potassium hydrogen phthalate, which neutralizes NaOH, in the ...

This was done by using a manual buret filled with titrant and adding each drop individually to an Erlenmeyer flask containing the sample solution (including the analyte to be measured) and the ...
