Potassium ethoxide since any transesterification reaction does not result in ester scrambling. Potassium ethoxide is stable, but also both flammable and corrosive. The compound reacts vigorously with water. If the compound comes into contact with damp air, it may lead to the heating and ignition of the solid powder. Keep separated from air, moisture, water, acids, oxidzing agents, and reducing agents. It can also cause severe skin burns. Potassium ethoxide Potassium ethoxide, also known as potassium ethanolate, is an off-white or yellow powder with the chemical formula of CHKO. Potassium ethoxide contains an ethoxide ion, the conjugate base of ethanol, which makes
Chemical substance FeS. The resulting compound has all the properties of a chemical substance and is not a mixture. Iron(II) sulfide has its own distinct properties such as melting point and solubility, and the two elements cannot be separated using normal mechanical processes; a magnet will be unable to recover the iron, since there is no metallic iron present in the compound. While the term "chemical substance" is a precise technical term that is synonymous with "chemical" for chemists, the word "chemical" is used in general usage in the English speaking world to refer to both (pure) chemical substances and mixtures (often
