noun / verb
sulfate
SUL-fayt/ˈsʌlfeɪt/
A compound or ion derived from sulfuric acid, or its application to something.
Blue copper sulfate crystals rest on the watch glass.

Etymology
The sulfur base identifies the element, while chemical -ate names salts corresponding to acids in -ic. Thus sulfate names a salt of sulfuric acid.
In context
this is also the number of sulfate ions as a result if all the sulfate ions could be turned into sulfuric acid then we would end up with one mole of sulfuric acid
