It contributes no color to sulfide salts. Sulfide is the main component of niningerite (niningerite is roughly 47% sulfide by mass), and contributes no odor to sulfide salts. As it is classified as a strong base, even dilute non-aqueous sulfide solutions are corrosive and attacks the skin. Sulfide is the simplest unary sulfur anion."@en ; skos:broader envthes:1 ; dc:created "2016-03-31"^^xsd:date ; skos:scopeNote "US LTER controlled vocabulary"@en ; skos:exactMatch . envthes:20871 skos:prefLabel "sulfide"@en ; a skos:Concept .
