Equilibria in aqueous solution. When MoO 3, molybdenum trioxide is dissolved in alkali solution the simple MoO 2− 4 anion is produced. As the pH is reduced the first species to be formed is the heptamolybdate rather than any of the smaller anions: . 7 MoO 2− 4 + 8 H + ⇌ Mo 7 O 6− 24 + 4 H 2 O . As the pH is decreased the octamolybdate is formed further anions with 8 and probably 16 ...

Applications of Molybdenum Metal and Its Alloys

Molybdenum is a transition metal, placing it in the center of the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. Molybdenum is a hard, silvery metal with a very high melting point. It is used primarily to make alloys with other metals.
