Strong and weak acids are important to know both for chemistry class and for use in the lab. There are very few strong acids, so one of the easiest ways to tell strong and weak acids apart is to memorize the short list of strong ones. Any other acid is considered a weak acid. There are only 7 common strong acids. Examples of ionization reactions include:.
All definitions agree that bases are substances which react with acids as originally proposed by G. Rouelle in the midth century. Such aqueous hydroxide solutions were also described by certain characteristic properties. They are slippery to the touch, can taste bitter  and change the color of pH indicators e. In water, by altering the autoionization equilibrium , bases yield solutions in which the hydrogen ion activity is lower than it is in pure water, i. Metal oxides , hydroxides, and especially alkoxides are basic, and conjugate bases of weak acids are weak bases.
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.
Acids and bases are used in many chemical reactions. They are responsible for most color change reaction and are used to adjust the pH of chemical solutions. Here are the names of some of the common acids and bases and the formulas associated with them. A binary compound consists of two elements. Binary acids have the prefix hydro in front of the full name of the nonmetallic element.
Acids are named by the anion they form when dissolved in water. Depending on what anion the hydrogen is attached to, acids will have different names. Simple acids, known as binary acids, have only one anion and one hydrogen. Most strong bases contain hydroxide, a polyatomic ion. Therefore, strong bases are named following the rules for naming ionic compounds. Weak bases made of ionic compounds are also named using the ionic naming system. For example, NH 4 OH is ammonium hydroxide.
There are three major classifications of substances known as acids or bases. This theory was developed by Svante Arrhenius in Later, two more sophisticated and general theories were proposed. The Lewis theory is discussed elsewhere. In , the Swedish chemist Svante Arrhenius proposed two specific classifications of compounds; acids and bases.

Strong and weak acids are key concepts in chemistry.
Acids and bases have been known for a long time. When Robert Boyle characterized them in , he noted that acids dissolve many substances, change the color of certain natural dyes for example, they change litmus from blue to red , and lose these characteristic properties after coming into contact with alkalis bases. In the eighteenth century, it was recognized that acids have a sour taste, react with limestone to liberate a gaseous substance now known to be CO 2 , and interact with alkalis to form neutral substances. In , Humphry Davy contributed greatly to the development of the modern acid-base concept by demonstrating that hydrogen is the essential constituent of acids. Around that same time, Joseph Louis Gay-Lussac concluded that acids are substances that can neutralize bases and that these two classes of substances can be defined only in terms of each other. The significance of hydrogen was reemphasized in when Carl Axel Arrhenius defined an acid as a compound that dissolves in water to yield hydrogen cations now recognized to be hydronium ions and a base as a compound that dissolves in water to yield hydroxide anions.

In this chapter learners will look at acids and bases. In Grade 11 learners were introduced to a lot of the concepts that are expanded on in this chapter. These include acid and base models and definitions, conjugate acid-base pairs, and some basic acid-base reactions. It is important that the learners have a good understanding of the work covered in Chapter 8 , specifically equilibrium constants, before studying this chapter. New concepts related to acids and bases will also be covered in this chapter.
Беккер узнал голос. Это девушка. Она стояла у второй входной двери, что была в некотором отдалении, прижимая сумку к груди. Она казалось напуганной еще сильнее, чем раньше.
Бросив быстрый взгляд на кабинет Стратмора, он убедился, что шторы по-прежнему задернуты. Сьюзан Флетчер минуту назад прошествовала в туалет, поэтому она ему тоже не помеха. Единственной проблемой оставался Хейл. Чатрукьян посмотрел на комнату Третьего узла - не следит ли за ним криптограф. - Какого черта, - промычал он себе под нос.
