Acid-Base Strengths of Organic Compounds By: Chris Frankmore Due Date: February 15‚ 2011 Resonance Benzenesulfonic Acid Benzoic Acid Benzyl Alcohol Benzylamine P-Cresol P-Toluidine Acid/Base | Structure | pH | Why It is a strong/weak acid/base | Benzenesulfonic Acid | | 1 | This is a strong acid because it has a pH of 1. Another reason why this is a strong acid is that its conjugate base has strong resonance stabilization

Carboxylic acids are compounds which contain a carboxyl group‚ -COOH group‚ where the -COOH group is attached either to a hydrogen atom or to an alkyl group. One of the example of carboxylic acid is benzoic acid( benzene carboxylic acid) which has a benzene connected to the carboxyl carboxyl group‚ -COOH group. It has a formula of C6H5COOH. The carbon atom of a carboxyl group has a high oxidation state. Therefore‚ that many of the chemical reactions used for their preparation are oxidations. In

Acid-Base Titration and Volumetric Analysis The purpose of this experiment is to determine the [NaOH] of a solution by titrating it with standard HCl solution‚ to neutralize a known mass of an unknown acid using the NaOH solution as a standard‚ to determine the moles of NaOH required to neutralize the unknown acid‚ and to calculate the molecular mass of the unknown acid. Procedure: Part A: Standarized 0.10M HCl solution and unknown NaOH solution were poured into two beakers. The burets

The type of acid was clearly controlled in the method. It clearly states that hydrochloric acid is representing the digestive chemical whilst the antacid tablets represent the food being digested. It is evident that the hydrochloric acid was the acid used in all aspects of this experiment successfully controlling this variable. It is not certain whether the amount of acid was controlled throughout the experiment. This is because the amount of acid was not clearly outlined neither

Acids‚ Bases‚ and Buffers Introduction: The pH scale is used to determine how acidic or basic a solution is‚ ranging from 1-14. The most acidic of all acids are at a pH level of 1 and the most basic of all bases are at 14. The neutral pH level is 7‚ which is what drinking water is. The pH level is determined by the amount of H+ ions present in a solution‚ and the more H+ ions there are the more acidic it is‚ and the lack of these ions results in more basic solutions. One distinguishing feature

Reacting Acids and Bases Lab Report Introduction Every liquid‚ except for distilled water‚ has either acidic or basic traits. An acid is sour tasting‚ and gives a sharp stinging pain in a cut or wound‚ and bases taste bitter‚ and feel slippery. A pH scale is used to determine what traits a liquid has; acidic or basic. The scale focuses on OH- (hydroxide ions) and H+ (hydrogen ions). The scale goes from 0 to 14. 7 is distilled water‚ as it is directly in the middle; neither acidic or basic. Acids are

Experiment E: Post lab Natasha Buckiewicz (130361780) IA: Matt Halloran Due: November 26‚ 2014 1. This experiment followed GCP number 8 which is reduce derivatives. This experiment did not use unnecessary derivation since the reaction was not modified in any way. No additional reagents were required so it did not generate a lot of waste. 2. Safer solvents and auxilaries (GCP #5) was not used in this experiment since the experiment used a solvent to complete the reaction. The reaction used both

Mejia Chem 101 Section ADF Lab 4: Weak Acid Unknown Procedure: When testing the acid‚ use only between 0.2 g and 0.3 g for each trial (get as precise a measurement as you can). The general procedure is to weigh out your acid‚ dissolve it in water‚ add a couple drops of the indicator (phenolphthalein)‚ and then add the sodium hydroxide until you note a color change (from clear to pink). When the color change occurs‚ you have added enough base to completely react with the acid (the endpoint). You are
