ACIDS AND BASES The reason that acid-base reactions are so important is that many of the things you come into contact with on a daily basis are either acids or bases. Most fruits are acids‚ as are carbonated beverages‚ tea‚ and battery acid. Common household bases include baking soda‚ ammonia‚ soap‚ and antacids. What are acids and bases? There are not one but three common definitions used to describe acids and bases: 1. Arrhenius acids and bases 2. Brønsted-Lowry acids and bases 3. Lewis acids

BRONSTED-LOWRY ACIDS AND BASES 1. The Bronsted-Lowry definition There are many definitions of acids and bases in existence‚ but the most useful one is the Bronsted-Lowry definition: An acid is a substance which can behave as a proton (re presented as a hydrogen ion‚ H+) donor. Any substance which contains hydrogen bonded to a more electronegative element can thus behave as an acid: HCl == H+ + Cl- H2SO4 == H+ + HSO4- A base is a substance which can behave as a proton acceptor.

Base Details Siegfried Sassoon’s epic war poem "Base Details" focuses on a soldier’s bitterness toward the fact that old men wage war while young men fight it. Sassoon uses various literary devices to express his anger toward such injustice. The main ones being rhyme‚ strong connotative words and especially diction. The speaker‚ a soldier in World War I‚ contemplates what it would be like to be an officer in during war. By using a sarcastic and cynical tone‚ he is effectively able to condemn war

However‚ section 2 subsection 5 provides that "the state shall provide adult citizens‚ the disabled and out-of-school youth with training in civics‚ vocational efficiency and other skills." The subsection strongly suggests that: 1) the education of handicapped students is not an integral part of the system of education as defined in subsection 1; and 2) the education

determined by colorimetric titration‚ and the identity of an unknown acid was determined by potentiometric titration. In the first titration‚ a strong acid standard‚ potassium hydrogen phthalate (KHP)‚ was used‚ to determine the concentration of a strong base‚ sodium hydroxide (NaOH). In order to do so‚ we prepared NaOH solution‚ prepared a buret‚ and standardized this solution by performing a colorimetric titration of the KHP with the solution until a color change was present. The color change was introduced

Base Details In the poem‚ “Base Details‚” Siegfried Sassoon expresses his great disgust towards the majors in the military. He is disgusted and appalled at the way the majors act while men are dying out in the battlefield. Sassoon is angered by the fact that the majors are living a life of luxury while sending young men “up the line” out into the battlefield. The title of the poem suggests these ideas. “Base” indicates a military installation‚ but another meaning is morally low; and the word “details”
