Acids and bases are compounds that, when added to an aqueous solution, change the amounts of H3O+ and OH- ions in solution. Acids increase the amount of H3O+ in solution by donating protons (H+) to water (H2O), forming H3O+. Bases increase the amount of OH- by removing protons from w...

Most people still assume that swimming pools are just holes in the ground, filled with water. In reality, there are actually many chemical processes, which occurs in a swimming pool, to keep the water clean and safe. Pathogens such as adenoviruses, Hepatitis A viruses, Shigella and Escherichia coli ...
