What Is the Freezing Point of Sulfuric Acid?
The freezing point of sulfuric acid is 37 degrees Fahrenheit, or 3 degrees Celsius, in a 98 percent solution where gravity is 1.84, nearly double that of water. Sulfuric acid's boiling point is 640 degrees Fahrenheit, or 338 degrees Celsius.
Sulfuric acid plays an important role in chemical industries due to the various chemical reactions for which the acid can be used. Some of the main functions are associated with petroleum refining, manufacturing of fertilizers and producing a number of chemicals, including drugs, dyes and sulfates. Large quantities of the acid are used in the steel and iron industry for cleaning manufactured metal.
