acidické

Acidické refers to a property of substances that indicates they have a pH value below 7. This means they contain a higher concentration of hydrogen ions (H+) than hydroxide ions (OH-) in an aqueous solution. Acids are a fundamental class of chemical compounds with distinct characteristics. They typically taste sour, although tasting unknown chemicals is strongly discouraged due to potential hazards. Many common substances are acidic, such as lemon juice, vinegar, and stomach acid. In chemistry, acids are often defined by their ability to donate a proton (H+) in a reaction, a concept central to the Brønsted-Lowry theory of acids and bases. Another definition, the Lewis theory, describes acids as electron-pair acceptors. The strength of an acid is determined by how readily it dissociates in water to release H+ ions. Strong acids, like hydrochloric acid, dissociate almost completely, while weak acids, such as acetic acid, only partially dissociate. Acids play crucial roles in numerous natural processes and industrial applications, including digestion, battery technology, and the production of fertilizers and plastics.
