CAS 7732-18-5: Water
Description:Water, with the chemical formula H₂O and CAS number 7732-18-5, is a vital and ubiquitous substance on Earth. It is a polar molecule, characterized by its bent shape, which results in a significant dipole moment. This polarity contributes to its excellent solvent properties, allowing it to dissolve a wide range of ionic and polar substances. Water has a high specific heat capacity, which enables it to absorb and retain heat, playing a crucial role in regulating temperatures in natural environments. It exhibits unique properties such as high surface tension and cohesion, which are essential for various biological processes. Water exists in three states: solid (ice), liquid, and gas (water vapor), with its phase transitions occurring at specific temperature and pressure conditions. Additionally, water has a high latent heat of vaporization, which is important for processes like cooling and climate regulation. Its density is highest at 4°C, which leads to ice floating on liquid water, an essential characteristic for aquatic ecosystems. Overall, water is fundamental to life, influencing chemical reactions, biological functions, and environmental systems.
