Copper Sulfate

The copper sulfate electrodes (Cu/CuSO 4) are the favorite reference for pipeline corrosion control since they are very stable and rugged for field use (Fig. 1.6).Most standard CP criteria to help determine adequate CP are related directly to the Cu/CuSO 2.Cu/CuSO 2 is traditionally used on soils and in fresh waters. Use in chloride environments and other contaminates can …

Chili Pepper Scoville Scale | ? SCOVILLESCALE

The Scoville scale exists since 1912 and was invented by the American pharmacologist Wilbur Scoville. It serves to determine the degree of pungency of fruits of the genus Capsicum, which includes peppers and chilis. The Scoville scale was originally based on the so-called Scoville Organoleptic Test developed by Wilbur Scoville.

What exactly is Mill Scale and what is done about it

2005. A. Mill scale consists primarily of magnetite, Fe 3 O 4, of characteristic blue-gray "steely" color. An extremely thin outer film of hematite, Fe 2 O 3, is invisible to the naked eye. The inner portion of the magnetite contains fine metal grains and sometimes, residual black FeO (see below), which contribute to the roughness of descaled metal.
