Years ago, sodium hypochlorite was used to chlorinate pools. It is basic, pH greater than 7. And I think ordinary hydrochloric acid was used to drop the pH back to 7. I don't know if these are still used. Sodium Hypochlorite ([math]NaClO[/math]) was used to chlorinate pools. If you want to lower the pH, try adding HCl.
Because most episodes of back pain have inflammation as a contributing factor, anti-inflammatory medication such as non-steroidal anti-inflammatory drugs (NSAIDs) is often an effective pain medication treatment option.
Nonsteroidal Anti-inflammatory Drug (NSAID. ), any of a large group of drugs that reduce pain and inflammation in muscles and joints. NSAIDs work by blocking the production of prostaglandins, body chemicals that cause inflammation and contribute to the brainâs perception of pain. NSAIDs are among the most commonly used drugs in the world.
