A bicarbonate indicator is a type of chemical compound or solution used to detect the presence of carbon dioxide (CO2) or the presence of bicarbonate ions (HCO3-) in a solution.

A bicarbonate indicator is a type of chemical compound or solution used to detect the presence of carbon dioxide (CO2) or the presence of bicarbonate ions (HCO3-) in a solution. Bicarbonate indicators are commonly employed in various applications, including in chemistry experiments, medical tests, and environmental analyses.
One well-known example of a bicarbonate indicator is “bromothymol blue.” This indicator changes color depending on the pH of a solution. In the presence of CO2, which can dissolve in water to form carbonic acid (H2CO3), the pH of the solution decreases, causing the bromothymol blue indicator to change from blue (indicating a higher pH, or more basic conditions) to yellow (indicating a lower pH, or more acidic conditions). This color change is due to the shifting equilibrium between carbonic acid and bicarbonate ions, and it’s often used to demonstrate the concept of acid-base equilibrium in educational settings.
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.
