Developed at the Carlsberg brewery, what scale measures the acidity of a liquid using a range of numbers from 0 to 14?
Søren Sørensen introduced the pH scale in 1909 to monitor beer fermentation at the Carlsberg Laboratory; the notation represents the power of hydrogen ions.
Which simple organic gas fuels most utility company pipelines?
Methane is the primary component of natural gas. Since it is naturally odorless, utility companies add mercaptan to give it a detectable rotten egg smell for safety.
Which chemical element forms the basis of all organic molecules?
Carbon can form four stable covalent bonds with other atoms. This allows it to create the complex chains and rings that form the basis of all organic molecules.
