a process called titration which‚ according to the Columbia Electronic Encyclopedia‚ is when you add a chemicals to a liquid in order to create a reaction which can determine the content of a substance inside the liquid. This is how you will find the Vitamin C content of different juices. Iodine will be added to the juice‚ which will create a reaction that can help determine the Vitamin C content. To start‚ pour 30 milliliters (mL) of Lugol’s solution into a 500 mL graduated cylinder. Add enough

Chemical reactions are a part of everyday lives. Whether it is the burning of propane at a kitchen stove‚ or washing detergent reacting with dirt stains‚ chemical reactions are useful tools that have widespread applications. With so many reactions assisting our everyday activities‚ it is important that ways to optimise reaction rates are investigated. “Reaction rate‚ the speed at which a chemical reaction proceeds… may be defined in terms of the amounts of the reactants consumed or products formed

From this lab we can learn to observe physical properties of varying substances as well as to use chemical reactions to observe chemical observe the chemical properties of varying substances. In experiment #1‚ we were able to detect physical properties of the aluminum and copper sulfate simply by looking at the substances. We then combined the two substances to see if they would create a chemical reaction and test the chemical properties. After being combined‚ bubbles and gas were created and the

The structure and synthesis of TPC is outlined in Scheme 1. Briefly‚ the compound 1 was synthesized as per literature procedure. 2 was synthesized by reacting 1-methy pyrazole-4-boronic pinacol ester with 1 by suzuki-coupling‚ the final product TPC was synthesized by treating with malononitrile in the presence of piperidine as a base and ethanol as solvent. The detailed synthesis procedure given in the experimental section. The structure and purity of TPC was unambiguously confirmed by 1H and 13C

The first step was to prepare 400 mL of an 0.1 M solution of NaOH. This was done by diluting from the 6 M solution that was provided. Next‚ 0.715g of KHP was weighed using the glazed paper and the triple beam balance. The KHP was then transferred to the 250 mL Erlenmeyer flask. Using a graduated cylinder‚ 50 mL of deionized water was measured and added to the flask. The KHP was dissolved in the water‚ and few drops of phenolphthalein were added. Moreover‚ the burette was rinsed with deionized water

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

sequence from Alcaligenes sp. JG3 was translated into amino acid sequence using two methods‚ manual translation and ExPASy online software. By manual method‚ amino acid sequence was obtained via codon translation one by one as shown in Figure IV.7. The sequence reference used is the lipase from A. faecalis MOR02 due to having high similarity with the lipase sequence from strain JG3 during CLUSTAL alignment and the alignment of the deduced amino acid with the referred sequence was carried out consecutively

Part 1. Hydrocarbon Nomenclature From International Union of Pure and Applied Chemistry (IUPAC) General Form of IUPAC Nomenclature [branching substituent(s)] Root [Suffix] Rules: 1. Identify the longest continuous chain of carbon atoms. This chain determines the parent name (root) of the alkane. The parent suffix for alkanes is‚ not surprisingly‚ -ane. For chains of equal length‚ pick the one with the most substituents. (Note: I number all possibilities going from left to right

Materials & Methods Synthesis Procedure of PDA@MT Polydopamine is synthesized through covalent polymerization similar to melanin biosynthesis‚ with DA oxidized to dopamine quinone‚ then further oxidized to DHI‚ which undergoes deprotonation and cross-linking via Michael addition to form PDA. A solution was prepared to synthesize PDA by mixing 90 mL of water‚ 40 mL of ethanol‚ and 3 mL of ammonia solution in a 300 mL beaker. After stirring for 30 minutes at 37°C‚ a solution of 500 mg of DA dissolved
