The Effects of Acid on Different Kinds of Metal | Sciencing
Iron is fairly reactive; in moist air. it oxidizes to form rust, a mixture of iron oxides. Oxidizing acids like nitric acid react with iron to form a passivating layer on the surface of the iron; this passivating layer protects the iron underneath from further attack by the acid, although the brittle oxides of the layer can flake off and leave the interior metal exposed.

ATSDR - Public Health Statement: Strontium
Jan 21, 2015· Strontium is a natural and commonly occurring element. Strontium can exist in two oxidation states: 0 and +2. Under normal environmental conditions, only the +2 oxidation state is stable enough to be important. Pure strontium is a hard, white-colored metal, but this form is not found in the environment. Rather, strontium is usually found in nature in the form of minerals.

Is Hydrochloric Acid or Phosphoric Acid Better for Scale
Phosphate ions can coine with calcium ions to form calcium phosphate, a highly insoluble compound. Because it can increase phosphate concentration and is a weaker acid, phosphoric acid is a less effective scale-removing agent than hydrochloric acid. Hydrochloric acid or sulfuric acid are more commonly used for industrial scale removal.
