👉 Cyaniding, also known as carbonic acid formation or carbonic acid precipitation, is a chemical reaction that occurs in certain environments where water exists. It involves the breakdown of carbon dioxide (CO2) into its component molecules, such as H2O and CO3²⁻ ions. The process begins when sunlight, air, or other sources of light trigger the decomposition of organic matter, particularly plant material, to produce oxygen gas and carbon dioxide gases. The carbon dioxide reacts with water in this
