Bromine water is a reddish-brown solution consisting of elemental bromine dissolved in water. This solution is commonly employed in laboratory settings to test for the presence of carbon-carbon double bonds (alkenes) in organic compounds. When bromine water is added to a sample containing an alkene, the brownish-red color of the solution fades as the bromine molecules react with the double bond, forming a colorless compound. This reaction, known as an addition reaction, serves as a visual indicator of the presence of unsaturation in the tested compound.
Beyond its role in organic chemistry, bromine water has been used as a disinfectant in water treatment due to its antimicrobial properties. However, it’s important to note that bromine water is corrosive, and elemental bromine can be harmful to the skin, eyes, and respiratory system. As such, it requires careful handling, appropriate personal protective equipment, and proper disposal practices to ensure safety in laboratory or industrial applications.

For many learners high school is not enough to prepare them for what they are to face at first year university. They find themselves completely overwhelmed and intimidated by what is expected of them to be able to do in a laboratory.
Unfortunately many learners who want to pursue science subjects go through this dilemma, few as they are because fact is SA is not producing enough learners who will become engineers, doctors, science researchers, let alone science innovators.
To address this, we developed a chemistry kits with 52 experiments for use by learners at home. This gives them an opportunity to gain hand-on exposure and engagement, confidence and understanding they need to study sciences further.
The kit comes with a manual explaining how science is experienced in daily life and therefore brings awareness of the application and usefulness of science, helping the learner relate to what they learn at school.
Some schools do have kits where only the teacher demonstrates the experiments and this is great, but you don’t master driving by watching the driving instructor, you must get in the driver’s seat yourself.
