Acids, Bases and Salts-Notes

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.

Acid–base reaction

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

Basically, acid-base reactions are chemical reactions with transfer of hydrogen cations protons. However, there are several concepts according to which acid-base reactions are defined differently. The terms pH value , acid-base titration , chemical equilibrium , stoichiometry and others are closely related to the topic.

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.

Acids have long been recognized as a distinctive class of compounds whose aqueous solutions exhibit the following properties:.

Section 14 - Acids and Bases

Generally, one question comes from this topic. Organic Acids are those acids which are obtained from plants and animals. Mineral Acids are those acids which are obtained from minerals. These acids are mostly asked in SSC Exams. Don't forget to remember this table. Present in.

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. Hydrochloric acid is neutralised by both sodium hydroxide solution and ammonia solution.

Все звонки принимались единственным оператором на двенадцатиканальный терминал Коренсо-2000. Телефонистка, державшая трубку у уха, мгновенно поднялась и поклонилась, увидев босса. - Садитесь! - рявкнул Нуматака.
