Lithium Hydroxide is a highly water insoluble crystalline Lithium source for uses compatible with higher (basic) pH environments. Hydroxide, the OH- anion composed of an oxygen atom bonded to a hydrogen atom, is commonly present in nature and is one of the most widely studied molecules in physical chemistry.
Jupiter, for instance, is made up mostly of trapped helium, hydrogen, and water. In our solar system, the four gas giants are Jupiter, Saturn, Neptune, and Uranus. Planets with their relative sizes to scale. The tiny bluish dot at the lower left is Earth.
Below this region Uranus appears to be composed of a mantle rich in water, methane, ammonia, and other elements. These elements are under high temperatures and pressures deep within the planet. The mantle is equivalent to 10 to 15 earth masses.
