One of the mysteries of the English language finally explained.
A strongly acid crystalline compound used in cleaning agents and to make weed killers.
Chemical formula: HOSO₂NH₂
- ‘All of the crystallized copper was enclosed in calcite, which was etched away with a sulfamic acid solution.’
- ‘The R1 working reagent contains 85 mmol / L of sodium acetate buffer, 110 mmol / L of sulfamic acid, surfactant, and ‘solubilizer.’’
- ‘When the calcite was dissolved with dilute sulfamic acid, it was noted that white semitranslucent florets of datolite occurred on the crystalline copper.’
- ‘In September 2002 Carlson sent samples of this material to Dan Behnke, who etched them with sulfamic acid to remove the calcite.’
- ‘It wasn't until a few days later, when the copper specimens had been cleaned in a sulfamic acid solution, that we realized what we had found.’
Mid 19th century: sulfamic from sulfur + amide + -ic.
