General Characteristics of Acids & Bases

Acids and bases are compounds with one important thing in common: When you immerse them in solution, they release free ions. Chemists measure the strength of an acid or base by its pH, which is a term that refers to the "power of hydrogen. Compounds with a pH lower than the midpoint value are acidic while those with a higher value are basic or alkaline. Acids taste sour while bases taste bitter. An acid reacts with metals to produce bubbles of hydrogen gas while a base feels slimy to the touch.

Many people enjoy drinking coffee. A cup first thing in the morning helps start the day. But keeping the coffee maker clean can be a problem. Lime deposits build up after a while and slow down the brewing process. The best cure for this is to put vinegar dilute acetic acid in the pot and run it through the brewing cycle. The vinegar dissolves the deposits and cleans the maker, which will speed up the brewing process back to its original rate. Just be sure to run water through the brewing process after the vinegar, or you will get some really horrible coffee.

21.1: Properties of Acids

Aqueous Arrhenius acids have characteristic properties which provide a practical description of an acid. Chemicals or substances having the property of an acid are said to be acidic. Common aqueous acids include hydrochloric acid a solution of hydrogen chloride which is found in gastric acid in the stomach and activates digestive enzymes , acetic acid vinegar is a dilute aqueous solution of this liquid , sulfuric acid used in car batteries , and citric acid found in citrus fruits. As these examples show, acids in the colloquial sense can be solutions or pure substances, and can be derived from acids in the strict [1] sense that are solids, liquids, or gases. Strong acids and some concentrated weak acids are corrosive , but there are exceptions such as carboranes and boric acid. The second category of acids are Lewis acids , which form a covalent bond with an electron pair. An example is boron trifluoride BF 3 , whose boron atom has a vacant orbital which can form a covalent bond by sharing a lone pair of electrons on an atom in a base, for example the nitrogen atom in ammonia NH 3.

Swedish Svante Arrhenius, in proposed the concept of acid and base based on the theory of ionization. This concept is only applicable to those compounds which dissolved in aqueous solution or you can say where water is the solvent. It covers many common acids, bases and their chemical reactions, but there are also other compounds that have the characteristics of acids and bases but they do not fit into Arrhenius concept.

Organic acids: Acids derived from living organisms like plants and animals. For example: citric acid is present in fruits, acetic acid present in vinegar, oxalic acid present in tomato, tartaric acid present in tamarind, lactic acid present in sour milk and curd. Mineral acids: They are also called inorganic acids. Strong acids: Completely dissociate into its ions in aqueous solutions. Weak acids: Weak acids are those acids which do not completely dissociate into its ions in aqueous solutions.

Chemistry: Properties of Acids and Bases

 Когда мы внесем эту поправку, - добавил Стратмор, - мне будет все равно, сколько ключей гуляет по свету: чем их больше, тем забавнее.  - Он жестом попросил ее возобновить поиск.  - Но пока этого не произошло, мы в цейтноте. Сьюзан открыла рот, желая сказать, что она все понимает, но ее слова были заглушены внезапным пронзительным звуком. Тишина шифровалки взорвалась сигналом тревоги, доносившимся из служебного помещения ТРАНСТЕКСТА.

Стратмор покачал головой: - Больше никто не знает о существовании кольца. Именно поэтому я и послал за ним Дэвида. Я хотел, чтобы никто ничего не заподозрил. Любопытным шпикам не придет в голову сесть на хвост преподавателю испанского языка. - Он профессор, - поправила его Сьюзан и тут же пожалела об .

Потом, всего через несколько секунд, он должен был включить основные генераторы, и сразу же восстановились бы все функции дверных электронных замков, заработали фреоновые охладители и ТРАНСТЕКСТ оказался бы в полной безопасности. Но, приближаясь к рубильнику, Стратмор понял, что ему необходимо преодолеть еще одно препятствие - тело Чатрукьяна на ребрах охлаждения генератора. Вырубить электропитание и снова его включить значило лишь вызвать повторное замыкание. Труп надо передвинуть. Стратмор медленно приближался к застывшему в гротескной лозе телу, не сводя с него глаз. Он схватил убитого за запястье; кожа была похожа на обгоревший пенопласт, тело полностью обезвожено.

Энсей Танкадо дразнит нас, заставляя искать ключ в считанные минуты. И при этом подбрасывает подсказки, которые нелегко распознать. - Абсурд! - отрезал Джабба.

Он целовал ее щеки. - Прости меня, - умолял. Сьюзан пыталась отстраниться, но он не отпускал. ТРАНСТЕКСТ задрожал, как ракета перед стартом.

 Выключите ТРАНСТЕКСТ! - потребовала. Остановка поисков ключа Цифровой крепости высвободила бы достаточно энергии для срабатывания дверных замков. - Успокойся, Сьюзан, - сказал Стратмор, положив руку ей на плечо.

 Как ты могла догадаться, - продолжал он, - вскоре я собираюсь выйти в отставку. Но я хотел уйти с высоко поднятой головой. Я хотел уйти с сознанием, что добился своей цели. - Но вы добились своей цели, - словно со стороны услышала Сьюзан собственный голос, - Вы создали ТРАНСТЕКСТ. Казалось, Стратмор ее не слышал.

Acids are substances that contain one or more hydrogen atoms that, in solution , are released as positively charged hydrogen ions.
