Baasilised

Baasilised refers to a class of chemical compounds that possess basic properties. In chemistry, a base is generally defined as a substance that can accept protons (H+ ions) or donate electrons. This definition is central to Brønsted-Lowry acid-base theory. Alternatively, according to the Lewis definition, a base is an electron-pair donor. Common examples of bases include hydroxides of alkali and alkaline earth metals, such as sodium hydroxide (NaOH) and calcium hydroxide (Ca(OH)2). These compounds often dissociate in water to produce hydroxide ions (OH-), which are responsible for their basic characteristics. Bases typically have a slippery feel and can taste bitter. They react with acids in a neutralization reaction to form salt and water. The pH scale is used to measure the acidity or alkalinity of a solution; substances with a pH greater than 7 are considered basic. Litmus paper, a common indicator, turns blue in the presence of a base. Bases are ubiquitous in both industrial processes and biological systems. For instance, ammonia (NH3) is a common industrial base used in the production of fertilizers and cleaning agents. In the human body, substances like bicarbonate ions (HCO3-) act as buffers to maintain a stable pH.
