Molybdates sentence example
- Molybdenum trioxide, like chromium trioxide, is an acidic oxide, and forms salts known as molybdates.
- The normal molybdates show a tendency to pass into polymolybdates.
- The molybdates are also capable of combining with other oxides (such as phosphorus and arsenic pentoxides) yielding very complex salts.
- The molybdates may be recognized by the fact that they give a white precipitate on the addition of hydrochloric or nitric acids to their solutions, and that with reducing agents (zinc and sulphuric acid) they give generally a blue coloration which turns to a green and finally to a brown colour.
