Alkalischen
Alkalisch (alkaline) refers to substances or solutions that exhibit basic properties, typically raising the pH above 7 when dissolved in water. In chemistry, alkaline substances are bases that can neutralize acids and often form hydroxide ions in aqueous solutions. The term is commonly used to distinguish soluble bases, or alkalis, from more insoluble basic oxides or salts.
There are several definitions of bases. The Arrhenius definition says bases produce hydroxide ions (OH−) in
Common examples of alkaline substances include sodium hydroxide (lye), potassium hydroxide, ammonium hydroxide (ammonia in water),
Natural environments can be alkaline as well. Alkaline soils have pH above 7 and can affect plant
