Acid–base titration is more than just mixing acids and bases — it’s a precise method to uncover unknown concentrations and chemical constants like pKa. By tracking pH changes as titrant is added, ...

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 ...

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 ...

Each chemical reaction involves an enthalpy change that leads to a change in temperature. The amount of substance converted during the reaction determines the increase (i.e. exothermic reaction) or ...
