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

Protecting our Special Places Mt Everest Mount Everest‚ also known in Nepal as Sagarmāthā and in Tibet as Chomolungma‚ is Earth’s highest mountain. It is located in the Mahalangur section of the Himalayas. Its peak is 8848m (29‚029 ft.) above sea level. The boarder between China and Nepal runs directly across the summit of Mount Everest. The current height was established by India and then confirmed in a subsequent survey by China in 1975. Due to Mount Everest being an amazing environmental feature

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. Any

Indicators can ten be used to test for the presence of acids or bases in a substance. Some are available in paper form (litmus) and others in liquid form (methyl orange).

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 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
