Most parts of our body (excluding things like stomach acid) measure around 7.2 and 7.6 on the pH scale (a 7 is neutral on the scale). If foreign strong substances dramatically change this pH, our bodies can no longer function properly. ...

WebSep 23, 2024 · Thus, if the p H is 3.5, the p OH must be 14 – 3.5 = 11.5. This relationship is quite useful as it allows you to quickly convert between p H and p OH, and therefore between [H 3 O +] and [HO – ]. We can now re-address neutrality in terms of the p H scale: A solution is acidic if p H < 7. A solution is basic if p H > 7. WebApr 10, 2024 · A recent New York Times article has unearthed the environmental footprint left by Bitcoin mining in the United States, painting a grim picture of its contribution to climate change.
