Ammonium chloride (NH₄Cl) is a white crystalline salt that dissolves easily in water and has a slightly salty taste. It is produced synthetically by combining ammonia and hydrochloric acid, though it also occurs naturally as a mineral called sal ammoniac, often found near volcanic areas.
Price range: R31.10 through R44.90
Ammonium chloride (NH₄Cl) is a white crystalline salt that dissolves easily in water and has a slightly salty taste. It is produced synthetically by combining ammonia and hydrochloric acid, though it also occurs naturally as a mineral called sal ammoniac, often found near volcanic areas. One of its primary uses is in agriculture, where it acts as a nitrogen-rich fertilizer to support the growth of crops like rice and wheat. Its high solubility makes it especially useful in areas with specific soil needs. Because it releases nitrogen slowly, it’s effective for maintaining soil fertility over time.
Beyond agriculture, ammonium chloride has a wide range of uses in medicine and industry. In healthcare, it’s commonly found in cough syrups as an expectorant, helping to break down mucus in the respiratory tract. It also appears in food manufacturing as a flavoring agent, especially in salty licorice popular in parts of Europe. Industrially, it’s used in metalworking to clean metal surfaces before soldering, and in battery production, particularly in older dry cell batteries. Its versatility and low cost make it a valuable compound across many fields.
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.
