potassium permanganate mixed with water produces nascent oxygen.
Nascent oxygen refers to highly reactive oxygen atoms that are formed by breaking down certain chemical compounds or through specific chemical reactions. These reactive oxygen atoms are important in various industrial processes, including water treatment and chemical synthesis.
Scientifically, nascent refers to a substance at the point at which it forms. In a chemical reaction, such as zinc reacting with sulphuric acid, individual hydrogen atoms will form but VERY quickly react with another atom to give H2 molecules. This is the only common situation in which atomic hydrogen exists, even if very fleetingly.
Most of the world's oxygen is produced by phytoplankton in the ocean through the process of photosynthesis. Land plants also play a significant role in oxygen production.
Oxygen bubbles are produced when water molecules are broken apart through photosynthesis or electrolysis. This process releases oxygen gas as a byproduct.
Oxygen in Earth's atmosphere is primarily produced through photosynthesis by plants, algae, and cyanobacteria. During photosynthesis, these organisms use sunlight to convert carbon dioxide and water into glucose and oxygen. Approximately half of the oxygen in Earth's atmosphere is produced by phytoplankton in the ocean.
