Pellets of soda lye (sodium hydroxide) Pellets of potash lye (potassium hydroxide)Lye is a hydroxide, either sodium hydroxide or potassium hydroxide.The word lye most accurately refers to sodium hydroxide (NaOH), [citation needed] but historically has been conflated to include other alkali materials, most notably potassium hydroxide (KOH).
When nitroglycerin explodes, the products after cooling are given by: 2 C 3 H 5 N 3 O 9 → 6 CO 2 + 5 H 2 O + 3 N 2 + O. The heat released can be calculated from the heats of formation. Using −371 kJ/mol for the heat of formation of condensed phase nitroglycerin [26] gives 1414 kJ/mol released if forming water vapor, and 1524 if forming ...

A 12% solution is widely used in waterworks for the chlorination of water, and a 15% solution is more commonly [39] used for disinfection of wastewater in treatment plants. Sodium hypochlorite can also be used for point-of-use disinfection of drinking water, [ 40 ] taking 0.2–2 mg of sodium hypochlorite per liter of water.
The contamination of U.S. drinking water with man-made "forever chemicals" is far worse than previously estimated with some of the highest levels found in Miami, Philadelphia and New Orleans, said ...
The EPA, which regulates public drinking water, advises a safety level of below 70 parts per trillion for the two most-studied PFAS chemicals. This is considered voluntary guidance. This is ...
