#alkaline

• Alkalescent — Becoming alkaline; showing a tendency to acquire basic (alkaline) properties, or having weakly expressed or developing alkaline characteristics. In biology, the term often describes substances or organic media undergoing a phase of slight alkalinization as a result of specific chemical reactions.
• Alcalia — A well-known brand of natural still mineral water, recognized in the market for its strongly alkaline character, featuring a high natural pH (typically around 9.36). It originates from a deep underground spring and is marketed within the context of a healthy lifestyle for its ability to support efficient hydration and help maintain the body's acid-base balance.
• Alkalic — Containing alkali; having basic or alkaline properties; alkaline. In geology and petrography, the term describes igneous rocks or minerals rich in alkali metals (such as sodium and potassium), characterized by a specific chemical composition that influences the structure and evolution of crustal melts.
• Alkaline — Pertaining to or characteristic of bases (alkali); having basic properties, characterized by a pH value greater than 7. In chemistry, the term describes solutions that neutralize acids or elements from the first group of the periodic table (alkali metals); in geology, it defines rocks or minerals rich in sodium and potassium oxides.
• Alkaline earth — Pertaining to or characteristic of the group of bivalent chemical elements in group 2 of the periodic table (such as beryllium, magnesium, calcium, strontium, barium, and radium). The name originates from the fact that the oxides of these metals exhibit pronounced alkaline properties and were historically called 'earths' due to their insolubility and high resistance to elevated temperatures.
• Alkaline therapy — A medical therapeutic method consisting of the internal or external administration of alkaline substances (such as sodium bicarbonate or alkaline mineral waters) for the purpose of neutralizing gastric hyperacidity, altering urinary pH, or correcting metabolic acidosis in the body. This structural treatment helps restore fluid homeostasis in various chronic diseases.
• Ammonium hydroxide — An aqueous solution of ammonium hydroxide (NH₄OH), a clear, colorless liquid with a pungent, suffocating, and strongly alkaline odor, obtained by dissolving ammonia gas in water; it is widely used in the chemical industry as a laboratory reagent, in producing nitrogen fertilizers, cleaning agents, textiles, or as a refrigerant medium.
