Practical Investigations
The Smart Wireless Colorimeter and Turbidity Sensor can be used to investigate a range of diverse scientific experiments:
- Rates of chemical reactions: determination of the rate and order
- Finding the value of an unknown concentration by the Lambert-Beer Law
- Investigations with enzymes: effects of temperature pH, inhibitors, enzyme kinetics
- Quantitative determination of biological molecules – sugars, protein, vitamins
- Quantitative determination of inorganic ions – nitrate, phosphate, chlorine, bromine
- Population growth of micro-organisms
- Cleanliness measurements of water
- Dosing biomass growth
- Algae bloom
- Phytoplankton development
- Sediment erosion
- Mud and silk deposition post storm activity
Example Data:
1. Demonstrating Turbidity Development: Sodium thiosulphate and hydrochloric acid, monitored using the turbidity function. The reaction produces a deposit that develops in time.
2. Demonstrating Reaction Rates: Sodium thiosulphate (variable) and hydrochloric acid Reaction, monitored using the colorimeter.
3. Storm surge turbidity measured days following the event.
