The Power point includes a video of an old Aspro Clear advert, which implies that soluble Aspirin is more effective than ordinary aspirin tablets due to it dissolving in the glass. I get participants ...

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 ...

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 ...

Lesson 8 for BTEC Level 3 Applied Science Unit 2 Aim A (Titrations and Colorimetry). This lesson covers the difference between end points and equivilance points, how to choose a suitable indicator and ...

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 ...

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 ...

pH is a measurable parameter between the values of 0 and 14, defining the acidity or alkalinity of a solution. Solutions with a pH = 7 are considered neutral, pH < 7 are considered acidic and pH > 7 ...

The acid dissociation constant, K a, and its negative decadic log, pK a, are key life sciences parameters that describe molecular acidity. Specifically, these values indicate the protonation state of ...
