- Why does drain cleaner get hot – an investigation into exothermic reactions
In this experiment, the temperature development that occurs when mixing a commercial drain cleaner (containing sodium hydroxide, NaOH) with water is investigated. Using a thermal imaging camera, the temperature change during the dissolution process is recorded. The goal of the experiment is to understand the thermal reaction and the associated heat development. Null Hypothesis: The …Continue reading “Why does drain cleaner get hot – an investigation into exothermic reactions”
- The Catalytic Effect of Ash on the Combustion of Sugar
This experiment investigates the catalytic effect of ash on the combustion of sugar. Initially, an attempt was made to ignite a sugar cube with a lighter, which was unsuccessful. Likewise, ash alone could not be ignited. However, after sprinkling ash onto the sugar cube, the mixture burned with a blue flame. This indicates that certain …Continue reading “The Catalytic Effect of Ash on the Combustion of Sugar”
- Production of Bath Bombs: Chemical Principles and Practical Protocol
Bath bombs are spherical or decoratively shaped solid bath additives that dissolve fizzingly in the bathwater, releasing fragrances, nourishing oils, and often colors. They are primarily used for skin care and relaxation. Their fizzing effect is based on a chemical reaction that occurs upon contact with water. In addition to the carbon dioxide produced, which …Continue reading “Production of Bath Bombs: Chemical Principles and Practical Protocol”
