A traditional method for the manufacture of KBr is the reaction of potassium carbonate with an iron(III, II) bromide, Fe 3 Br 8, made by treating scrap iron under water with excess bromine: [4] 4 K 2 CO 3 + Fe 3 Br 8 8 KBr + Fe 3 O 4 + 4 CO 2 {\displaystyle {\ce {4 K2CO3 + Fe3Br8 -> 8 KBr + Fe3O4 + 4 CO2}}}

For example, the melting point of silicon at ambient pressure (0.1 MPa) is 1415 °C, but at pressures in excess of 10 GPa it decreases to 1000 °C. [13] Melting points are often used to characterize organic and inorganic compounds and to ascertain their purity. The melting point of a pure substance is always higher and has a smaller range than ...
