And when an acid was added chromate turned orange while dichromate remained orange. The acid solution used was H2SO4 because it is highly acidic. 2CrO4-2(aq) + 2H3O+(aq) ⇄ 3H2O(L) + Cr2O7-2(aq) is the balance chemical equation of the system. When the acid solution is added the equilibrium shifts to the left making the solution orange and when basic solution is added to the solution

EXTRACTION OF BENZOIC ACID‚ 2-NAPHTHOL‚ AND NAPHTHALENE FROM UNKNOWN SAMPLE # 131 Douglas G. Balmer (T.A. Mike Hall) Dr. Dailey Submitted 11 July 2007 Introduction: The purpose of this experiment was to separate a sample of benzoic acid‚ 2- naphthol‚ and naphthalene of unknown proportions using a two-base extraction method. The three components of the mixture will react differently to sodium bicarbonate and sodium hydroxide because each of the bases’ conjugate acids has a different pKa. The

Acid-Base Extraction: Separation of an Organic Acid‚ Base and a Neural Compound Introduction/Background Acid base extraction is a widely used commercial method in separating acids‚ bases and neutral compounds. This is concept is based on several physical properties of the compounds‚ such as boiling point‚ melting points and solubility. The different solubility properties of the protonated and non-protonated forms of these compounds depend on the functional groups present‚ such

recrystallization‚ the percentage purity of solid C was found to be 6.01%. The melting point range of purified solid C was 117.0 – 119.0C while the boiling point of liquid C was found to be 117C. The identity of solid C and liquid C was found to be benzoic acid and butyl acetate respectively. INTRODUCTION The isolation of individual or groups of compounds can be accomplished

Chris Archbold Argumentative Synthesis Prof. McKee 17 April 2013 Argumentative Synthesis on Skateboarding Skateboarding is a sport that is uniquely different from all others. It doesn’t require a team competing for a common goal. There isn’t a legitimate system that judges how talented a skateboarder is. There is no league regulating how skateboarding should be done. Skateboarding is an individualistic sport that provides infinite potential for progression. There is no limit on the amount

Amino Acids Amino acids are biologically organic compounds containing amine and carboxylic acid functional groups‚ usually along with a side-chain specific to each amino acid. The elements that are key of an amino acid are carbon‚ hydrogen‚ oxygen‚ and nitrogen. There are about 500 different kinds of amino acids found but we recognize 23 of the amino acids that are known‚ they are classified into three groups‚ essential semi-essential‚ and non-essential. Each amino acid has unique characteristics
