Explanation of every important term related to Acids and Bases. The main points of the chapter 2 is covered through these notes.

This page describes the Arrhenius, Bronsted-Lowry, and Lewis theories of acids and bases, and explains the relationships between them. It also explains the concept of a conjugate pair - an acid and its conjugate base, or a base and its conjugate acid. The Arrhenius theory is of historical interest only, and you are unlikely to need it unless you are doing some work on the development of ideas in chemistry.

Indicators: Indicators are substances which indicate the acidic or basic nature of the solution by the colour change. Types of Indicator: There are many types of indicators. Some common types of indicators are:. Natural Indicators: Indicators obtained from natural sources are called Natural Indicators.

Chemistry Notes on Acids and Base for Railways & SSC Exam

Acids have long been recognized as a distinctive class of compounds whose aqueous solutions exhibit the following properties:. Acidic solutions have a pH less than 7, with lower pH values corresponding to increasing acidity. Common examples of acids include acetic acid in vinegar , sulfuric acid used in car batteries , and tartaric acid used in baking. The strength of an acid refers to how readily an acid will lose or donate a proton, oftentimes in solution. A stronger acid more readily ionizes, or dissociates, in a solution than a weaker acid. The six common strong acids are:. By contrast, however, a weak acid, being less willing to donate its proton, will only partially dissociate in solution.

An acid—base reaction is a chemical reaction that occurs between an acid and a base. It can be used to determine pH. Their importance becomes apparent in analyzing acid—base reactions for gaseous or liquid species, or when acid or base character may be somewhat less apparent. The first of these concepts was provided by the French chemist Antoine Lavoisier , around It is important to think of the acid-base reaction models as theories that complement each other. The first scientific concept of acids and bases was provided by Lavoisier in around The Lavoisier definition held for over 30 years, until the article and subsequent lectures by Sir Humphry Davy in which he proved the lack of oxygen in H 2 S , H 2 Te , and the hydrohalic acids.

Acid Base and Salt Notes The taste of the food varies because each food item has a unique chemical composition. Based on their chemical nature, substances can be categorized into acids, bases and salts. Acids: Acids are compound in which one of the elements that makes up the acid molecule is always the hydrogen element.

It conducts electricity. Acids when dissolved in water release large amount of heat. If water is added to concentrated acid then the heat generated may cause the mixture to splash out and cause bums. Hence to avoid burns acid must be added drop wise into water with constant stirring. So that the heat generated spreads over in water. Bases soluble in water are called alkalis.

 Какого черта ему здесь надо? - спросил Стратмор, как только они с Сьюзан оказались за дверью Третьего узла. - Как всегда, валяет дурака, - сказала Сьюзан. Стратмор не скрывал недовольства. - Он ничего не спрашивал про ТРАНСТЕКСТ. - Нет.

Jerez. Откуда-то сверху накатывали приглушенные волны классической музыки. Бранденбургский концерт, - подумал Беккер.

Не удастся отслеживать перемещение грузов наркокартелей, крупные корпорации смогут переводить деньги, не оставляя никакого следа и держа Налоговое управление в полном неведении, террористы будут в полной тайне готовить свои акции. Результатом будет полнейший хаос. - А Фонд электронных границ будет праздновать победу, - побледнела Сьюзан.

 Un punqui. - Si. Punqui. - Панк. - Да, панк, - сказала Росио на плохом английском и тотчас снова перешла на испанский.  - Mucha joyeria.

Моя интуиция подсказывает мне… - Что ж, ваша интуиция на сей раз вас обманула, мисс Милкен. В первый раз в жизни. Мидж стояла на своем: - Но, сэр. Коммандер Стратмор обошел систему Сквозь строй. Фонтейн подошел к ней, едва сдерживая гнев. - Это его прерогатива. Я плачу вам за то, чтобы вы следили за отчетностью и обслуживали сотрудников, а не шпионили за моим заместителем.


Acid-Base Chemistry. ▫ There are a couple of ways to define acids and bases. ▫ Brønsted-Lowry acids and bases. ▫ Acid: H+ ion donor. ▫ Base: H+ ion.

 Вирус. - Никакого вируса. Выслушай меня внимательно, - попросил Стратмор. Сьюзан была ошеломлена. ТРАНСТЕКСТ еще никогда не сталкивался с шифром, который не мог бы взломать менее чем за один час. Обычно же открытый текст поступал на принтер Стратмора за считанные минуты.

Даже перепачканная сажей и промокшая, Сьюзан Флетчер производила более сильное впечатление, чем он мог предположить.

Basically, acid-base reactions are chemical reactions with transfer of hydrogen cations protons.
