Potassium hydrogen sulfate (also known as potassium bisulfate), KHSO 4, is readily produced by reacting K 2 SO 4 with sulfuric acid. It forms rhombic pyramids, which melt at 197 °C (387 °F). It dissolves in three parts of water at 0 °C (32 °F). The solution behaves much as if its two congeners, K 2 SO 4 and H 2 SO 4, were present side by ...

Potassium chromium sulfate. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Chrome alum or Chromium (III) potassium sulfate is the potassium double sulfate of chromium. Its chemical formula is KCr (SO 4) 2 and it is commonly found in its dodecahydrate form as KCr (SO 4) 2 ·12 (H ...
Potassium alum, potash alum, or potassium aluminium sulfate is a chemical compound first mentioned under various Sanskrit names in Ayurvedic medicinal texts such as charak samhita, sushrut samhita, and ashtang hridaya; is chemically defined as the double sulfate of potassium and aluminium, with chemical formula KAl(SO 4) 2.
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) Potassium bisulfate (potassium bisulphate) is an inorganic compound with the chemical formula KHSO 4 and is the potassium acid salt of sulfuric acid. It is a white, water-soluble solid.
Major potassium chemicals are potassium hydroxide, potassium carbonate, potassium sulfate, and potassium chloride. ... 47% K and 41% Cs has the lowest melting point ...
1802 K. 1529 °C. 2784 °F. The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
In contrast potassium is near the top of the reactivity series, and potassium sulfate (K 2 SO 4) does not decompose at its melting point of about 1,069 °C (1,342 K; 1,956 °F), nor even at its boiling point.
