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 ...

In this segment, the students discuss the data from their titration lab. Our host explains the importance of titration in real world applications and discusses auto ionization of water and the ...

This lab includes the complete titration procedure used to investigate how well a buffer resists changes in pH. Prepare a buffer solution by accurately calculating and measuring the required amounts ...

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 ...

Titration instruments are used to determine the concentration of dissolved substances. Titration is based on a complete chemical reaction between the analyte and a reagent or titrant of known ...

The students use litmus paper to determine the acidity of different substances and discuss the Bronsted-Lowry Model, the Arrhenius Model, and the Lewis Model. They measure the pH of different ...

Karl Fischer titration is based on a reaction that consumes the water present in the sample tested. The end-point is determined by the absence of any waterand when the iodine titrant reaches excess in ...

The titration reaches its endpoint when the titrating agent has achieved a volume sufficient to react the total amount of water in the sample. Water and iodine are used up in an equimolar ratio. The ...
