Sulfatfällningar
Sulfatfällningar refers to the process where sulfate ions react with cations in a solution to form insoluble precipitates. This phenomenon is significant in various chemical and environmental contexts. A common example is the precipitation of barium sulfate (BaSO4) when barium ions (Ba2+) are introduced to a solution containing sulfate ions (SO42-). Barium sulfate is known for its very low solubility in water, making it an effective scavenger of sulfate.
Another important precipitation reaction involves calcium sulfate (CaSO4), also known as gypsum. Calcium sulfate is less
In environmental science, sulfatfällningar plays a role in natural water purification processes and can also be
