Melting temperature is a confusing area.

Hydrochloric acid - Wikipedia

2019-5-9 · Hydrochloric acid or muriatic acid is a colorless inorganic chemical system with the formula H 2O:HCl. Hydrochloric acid has a distinctive pungent smell. It is classified as strongly acidic and can attack the skin over a wide composition range, since the hydrogen chloride completely dissociates in aqueous solution. Hydrochloric acid is the

The Whys and Hows of Hydrochloric Acid Pickling

2006-4-6 · Hydrochloric acid dissolves scale rapidly, so these accumulations do not occur. Also, at high temperatures, in sulfuric acid, ferrous sulphate monohydrate forms and settles out in the tanks, due to decreasing solubility at higher temperatures; this does not happen with hydrochloric acid. Of course, hydrochloric acid has its disadvantages too:

Calcium chloride - Wikipedia

2019-5-5 · Calcium chloride has a very high enthalpy change of solution, indied by considerable temperature rise accompanying dissolution of the anhydrous salt in water. This property is the basis for its largest-scale appliion. Molten calcium chloride can be electrolysed to give calcium metal and chlorine gas: CaCl 2 → Ca + Cl 2 Preparation

Chloride/Chlorine Levels and Stainless Steel Alloy

The 304 and 304L (18-8 stainless steel alloys) have been utilized very successfully in fresh waters containing low levels of chloride ion of up to 100 ppm. This level of chloride is considered to be the limit for the 18-8 alloys, particularly if crevices are present. Higher levels of chloride might cause crevice corrosion and pitting.
