Superacids can turn carbon molecules into diamondsSefa Kart/AlamyWater may transform into a superacidic fluid under extreme heat and pressure. These conditions are found only in Earths interior, within icy planets like Uranus and Neptune and possibly in controlled laboratory experiments.Under immense pressures and temperatures, water exhibits a remarkable property it becomes an exceptionally potent acid, also known as a superacid, which can be billions or even trillions of times stronger than sulphuric acid, says Flavio Siro Brigiano at Sorbonne University in France.This
