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 ...

A range of production processes frequently employ acid mixtures comprised of two or three acids; for example, nitric acids, sulfuric acids and hydrochloric acids. In order to use these acids safely ...

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 ...
