Cobalt chloride is well-known for its ability to change color based on humidity, making it useful as a moisture indicator. When exposed to moisture, the anhydrous blue form absorbs water and turns pink, while losing water reverses the color change.
In addition to its use as a humidity indicator, cobalt chloride is employed in laboratories for various chemical reactions, in the preparation of other cobalt compounds, and in electroplating. However, it is toxic and should be handled with caution, as it can cause skin irritation and other health hazards.
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.
