K2SO6, also known as Potassium sulfate or Sulfate of potash in English, is a chemical compound that exists in the form of white crystals. The molar mass of K2SO6 is 174.259 g/mol. The molecular structure of K2SO6 consists of two potassium atoms (K), one sulfur atom (S), and six oxygen atoms (O). Its ionic structure consists of two potassium ions (K+) and one sulfate ion (SO42-).
In terms of properties, K2SO6 is a white, odorless solid with a neutral pH. It does not react with metals and non-metals, but can react with acids to form salts and water. For example, if you react K2SO6 with H2SO4, you will get KHSO4 and H2O.
K2SO6 is commonly used in the production of fertilizers, as it provides potassium, a necessary nutrient for plants. To prepare K2SO6, you can react potassium hydroxide (KOH) with sulfuric acid (H2SO4), producing potassium sulfate salt and water. This reaction can be carried out both in laboratories and industrially.
