Analytical Chemistry Lab B Titrations – Level 1 – 360° Interactive Exercise

Welcome to a titration health and safety 360° “bad lab” exercise. This interactive activity allows you to progress through three levels.

This is level 1. Move through the scene and try to identify as many health and safety hazards, or examples of poor practice, as you can. Look for the key within the scene and this will allow you to progress to the next level (see right). More guidance on each level further below.

General guidance on the levels: Each level is slightly different with decreasing levels of guidance as you progress. All levels offer points for discussion between learners.

Level 1: You will see 3 or 4 images within the scene without any hints. As you progress, you will see the same images containing blue numbered dots to highlight the areas with health and safety issues. The blue numbered dots correspond to the hint button below.

Level 2: Same as level 1 except the blue dots do not contain any numbers and there is no additional hints.

Level 3: The scene presented offers no specific hints except to indicate the extent of health and safety issues.

1. The burette should be clamped perpendicular to the bench.
2. The base plate of the clamp stand should be under the conical flask.
3. Ensure the end of the burette is just above the flask.
4. Gloves may be necessary depending on the chemicals in use.
5. Placing a white base under the flask makes it easier to spot colour changes.
6. Unlabelled flask / Dispose of waste appropriately.


Additional activity: Can you spot any additional titration health and safety issues that have not been highlighted?

Disclaimer: We have deliberately introduced health and safety issues into these titration scenes for educational purposes.  We do not condone bad lab practice, but allowing learners to see such scenarios can help develop hazard perception skills and a general appreciation of health and safety. We have not highlighted all hazards in these exercises. Best practice may differ in your institution so please discuss this with a local instructor.

Which key did you spot in the scene? Select the correct option below to access level 2.
