WebAn acid is a proton donor. Monoprotic acids donate just one proton per acid molecule in a solution, whilst diprotic acids donate two. The word for acid comes from the Latin term ‘ acidus ’, signifying sour. Acids turn damp blue litmus paper red. In contrast, bases turn red litmus paper blue and have a soapy texture. WebArrhenius theory, theory, introduced in 1887 by the Swedish scientist Svante Arrhenius, that acids are substances that dissociate in water to yield electrically charged atoms or molecules, called ions, one of which is a hydrogen ion (H+), and that bases ionize in water to yield hydroxide ions (OH−). It is now known that the hydrogen ion cannot exist alone in …
WebFor example, the reaction of sulphuric acid with zinc. H 2 S O 4 + Z n → Z n S O 4 + H 2. Alkalis (bases that are soluble in water) react with metals to produce salt and hydrogen gas.
