The typical concentration of sodium fluoride (NaF) in test tube experiments varies widely from 0.1 ppm to 2% (20,000 ppm) depending on the scientific purpose.
Tap water concentrations in parts per million (ppm) are reported for fluoride rather than sodium fluoride itself, with a recommended optimal level of 0.7 ppm (0.7 mg/L) in U.S. fluoridated water systems.
The sheer exhaustion of having to argue one’s case for the right to argue one’s case, in the face of unending bad faith, is mind-numbing. Thanks to all who persevere.
