Base (chemistry)

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.

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.

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.

Base (chemistry)

Strong and weak acids are key concepts in chemistry. Strong acids completely dissociate into their ions in water, while weak acids incompletely dissociate. There are only a few strong acids, but many weak acids. Strong acids completely dissociate in water into their ions and produce one of more protons or hydrogen cations per molecules. Mineral or inorganic acids tend to be strong acids.

Strong and weak acids are important to know both for chemistry class and for use in the lab.

The Arrhenius Definition of Acids and Bases

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.

Проснувшись утром в своей постели, Беккер заканчивал день тем, что ломился в гостиничный номер незнакомого человека в Испании в поисках какого-то магического кольца. Суровый голос Стратмора вернул его к действительности. Вы должны найти это кольцо. Беккер глубоко вздохнул и перестал жаловаться на судьбу. Ему хотелось домой. Он посмотрел на дверь с номером 301.

Нигде не должно остаться даже намека на Цифровую крепость.

Внезапно он взвился в воздух и боком полетел вниз, прямо над Беккером, распростертым на животе с вытянутыми вперед руками, продолжавшими сжимать подсвечник, об который споткнулся Халохот. Халохот ударился сначала о внешнюю стену и только затем о ступени, после чего, кувыркаясь, полетел головой. Пистолет выпал из его рук и звонко ударился о камень.

Кассирша сощурилась. - Вашей возлюбленной пятнадцать лет. - Нет! - почти крикнул Беккер.  - Я хотел сказать… - Чертовщина.
