Corrosive agents
HCl
Hydrochloric Acid
塩酸AcidStrong
A typical strong acid. Dissolves many metals but ineffective against noble metals.
H₂SO₄
Sulfuric Acid
硫酸AcidStrong
King of industry. Properties change significantly with concentration. Concentrated form has oxidizing power.
HNO₃
Nitric Acid
硝酸OxidizerStrong
Powerful oxidizer. Passivates many metals but dissolves copper. Component of aqua regia.
H₃PO₄
Phosphoric Acid
リン酸AcidModerate
Medium-strength acid. Notably forms a phosphate protective film on iron, and is used industrially as a rust-converter coating.
CH₃COOH
Acetic Acid
酢酸AcidWeak
Weak organic acid (main component of vinegar). Slowly corrodes many metals; lead and zinc are notably attacked.
H₂CO₃
Carbonic Acid
炭酸AcidWeak
Weak acid formed when CO₂ dissolves in water. Found in rainwater and carbonated drinks; slowly corrodes iron and zinc over long exposure.
O₃
Ozone
オゾンOxidizerModerate
Powerful oxidizer. Degrades rubber and oxidizes many metal surfaces.
NaOH
Sodium Hydroxide
水酸化ナトリウムAlkaliStrong
Strong alkali. Dissolves amphoteric metals (Al, Zn, Sn). Also known as caustic soda.
