Reagent, A.C.S.

This B&A Fine Chemical is notable for its uniform quality—lot after lot, year after year. Three strengths—all Reagent, A.C.S. grade—are available. They assay 70-72%, 60% and 20% min. HC104 thus providing a product suitable for any of the acid's uses which include: manufacture of explosives and matches; electropolishing of steel, stainless steel, brass, nickel, copper and certain other metals; bright dipping of cadmium and zinc plates; and, as a cathode treating agent in electrodeposition of copper powder.

B&Α FERROUS AMMONIUM SULFATE Technical and Crystal, Reagent, A.C.S.

Two Reagent grades are offered, both assaying 99.5% min. FeSO4 ( N H 4 ) 2 S O 4 · 6 Η 2 O . Their purity is superior to that required by A.C.S. specifications, the Reagent Special grade being particularly low in manganese. Many industrial users will find the Technical grade suitable for their needs since the fine uniform crystal available is low in insolubles and assays 9 8 % min. Some of the applications for Ferrous Ammonium Sulfate are in the manufacture of iron blue; in the metal industry as an ingredient of brass coloring baths and iron plating solutions; and as a substitute for ferrous sulfate in a number of fields.

B&A CUPRIC NITRATE Purified and Crystal, Reagent, A.C.S.

Both grades of this B&A Quality chemical assay 99.5% min. Cu ( N 0 3 )2 · 3 H 2 0 . The Reagent reaches a purity even higher than that of A.C.S. requirements and is particularly low in metallic impurities, especially iron and nickel. Industry will find the Purified material suitable for most uses since this product is not only low in insolubles but also is controlled within close limits on neutrality. The range of uses for Cupric Nitrate is wide, covering such applications as manufacture of pure cupric oxide used as a petroleum catalyst; manufacture of fire-place salts and pyrotechnics; ingredient in baths and solutions for blackening copper and copper alloys, iron and zinc; sensitizer in photographic emulsions; and as a mordant in textile dyeing.
