Two key factors that contribute to the ease of deprotonation are the polarity of the H—A bond and the size of atom A‚ which determines the strength of the H—A bond. Acid strengths are also often discussed in terms of the stability of the conjugate base. Sulfonic acids‚ which are organic oxyacids‚ are a class of strong acids. A common example is toluenesulfonic acid (tosylic acid). Unlike sulfuric acid itself‚ sulfonic acids can be solids. Superacids are acids stronger than 100% sulfuric acid. Examples

CHEMICAL REACTIONS: ACID-BASE BUFFERS Short Overview Acids and bases represent two of the most common classes of compounds. Many studies have been done on these compounds‚ and their reactions are very important. Perhaps the most important reaction is the one in which an acid and base are combined‚ resulting in the formation of water (in aqueous solution) and a salt; this reaction is called neutralization. A buffer solution is a solution that contains both an acid and a salt

Worksheet - Acids‚ Bases and Salts 1. I am pure water. When heated my pH (increases‚ decreases)‚ because more of my water molecules dissociate. 2. I am a 0.020 M solution of weak acid‚ HA. If I only dissociate to the extent of 1.50%‚ what is the value of my Ka? 3. I am a 0.20 M solution of hydrocyanic acid‚ HCN‚ with a Ka of 4.93 x 10¯ 10 . What is my pH? 4. I am a buffer made from 0.10 M acetic acid and 0.15 M sodium acetate. If the Ka for acetic acid is 1.77 x 10¯ 5 ‚ what is my pH? 5. I am

What Explains the Rapid Growth in the Internet? In these few centuries‚ the broadcasting industries have a few significant transformations. The broadcasting radio industry expanded rapidly in 1920s until the born of television service in 1936. However‚ the born of broadcasting television service did not influence broadcasting radio industry very much. In fact‚ the real challenger of broadcasting industries is Internet‚ which was growth rapidly in these two decades. This essay is mainly divided

BasesLewis acids and bases play an important role in chemical reactions because‚ except oxidation-reduction reactions‚ almost every reaction could be categorized as an acid-base reaction. Bases in water solutions show certain specific characteristics: bitter taste‚ feel slippery‚ and turn litmus paper blue. Acids in water solutions show these most common characteristics: sour taste‚ react with metals‚ and turn litmus paper red. The understanding of chemical reactions‚ such as acid and base interactions‚

ACID BASE IMBALENCE INTRODUCTION The body normally maintains a steady balance between acids‚ produced during metabolism and bases that neutralize and promote the excretion of the acids.Many health problems may lead to acid base imbalance.Patients with Diabetis mellitus ‚COPD‚and kidney disease frequently frequently develop acid base imbalences. Vomiting and diarrhea may also cause acid base imbalance.The kidneys are an essential buffer system for

In order to destroy all that is not the Caliphate‚ this terrorist group has implemented strategies to successful conquer world domination. This global strategy involves Iraq and Syria‚ Middle east and North Africa‚ along with individual implementation in all areas of the globe. The main strategy is to take on powerful countries‚ forcing them to lack the ability to fight against the attacks of ISIS‚ and essentially for them to cut-and run-in the face of these brutal attacks (Walter‚ 2015).

STANDARDIATION OF ACID AND BASE Eunice Ivy B. Gamboa ABSTRACT Solutions of known concentration are prepared by dissolving measured masses of standard acids in distilled water. The concentrations of unknown solutions of sodium hydroxide are determined by titration. An acid solution reacts with a base solution in a "neutralization" reaction. Titrations permit the concentrations of unknown acids/bases to be determined with a high degree of accuracy. In order to analyze unknown acids/bases‚ we must have a "standard"
