and is a strong acid. Where comparing to the conductivity of distilled water to HCL would be evidently HCL. This is because distilled water doesn’t contain ions‚ hence no movement of electrons‚ furthermore no conductivity. However since we added sodium chloride‚ distilled water will have some conductivity but no where near the amount of HCL. Comparing to the conductivity of vinegar to HCL mostly relays on how acidic each other are. Since HCL is a strong acid and vinegar is a weak acid‚ this will impact

took my first chemistry class I became mesmerized with the field of chemistry. The idea that I could start with one molecule and change it into a completely different compound both fascinated and thrilled me. I was at a predicament‚ on one hand I wanted to study medicine to help people‚ but I was far more interested in and passionate about the chemical processes and reactions. This changed when I took my first organic chemistry class. I want to make a career by applying chemistry to medicine and

a small magnetic stir bar. A 30-cm reflux condenser was attached to the round bottom flask and a gas inlet was then connected to the condenser and to the bubbler. Since Mo(CO)6 and the product tends to react with oxygen at high temperatures this reaction must take place in an inert atmosphere. Therefore‚ the gas inlet was connected at the top of the condenser to a nitrogen source and was flushed with a stream of nitrogen of approximately 5 minutes. A rheostat-controlled heating mantle was used to

Title: Studying SN1 and SN2 Reactions: Nucleophilic Substitutions at the saturated carbon Lab Partner: Jeszie Geronimo Objective and purpose: the purpose of this experiment is to convert a primary alcohol to an alkyl bromide using a Sn2 Reaction. Investigate some factors that influence the rate of Sn1 reactions. The second part of this lab will focus more on how unlike factors influence the rate of reactions in anSN1 reactions. The factors that we will be inspecting are the leaving groups‚ Cl-

nCH3 The first step in the lab is the preparation of the solvent used in the developing chamber for thin layer chromatography. The solvent used is a 3:1 mixture of toluene and petroleum. After the developing chamber is prepared‚ it is essential to begin preparation of the unknown DNPH derivative[6]. The preparation of the 1‚2 DNPH derivative of a ketone is in fact a small organic synthesis which produces a fraction of a gram of product. The second part of the lab makes use of NMR Spectrometry

Kong Acid rain on plant -Background information Unpolluted rain is normally slightly acidic‚ with a pH of 5.6. Carbon dioxide (CO2) from the atmosphere dissolves to form carbonic acid. Acid rain is rain that has been made acidic by certain pollutants in the air. Acid rain is a type of acid deposition‚ which can appear in many forms. Wet deposition is rain‚ sleet‚ snow‚ or fog that has become more acidic than normal. Dry deposition is another form of acid deposition‚ and this is

SYNTHESIS AND CHEMISTRY OF K2S2O8 ABSTRACT In this experiment‚ a sample of K2S2O8 was prepared by the electrolysis of an aqueous solution of H2SO4 and K2SO4. The peroxodisulfate anion‚ S2O82-‚ was also observed for its ability to serve as a counterion for precipitation by preparing a copper (II) complex by reacting hydrated copper (II) sulfate with ammonium peroxodisulfate in the presence of pyridine. This same ability‚ coupled with its strong oxidizing ability allowed for stabilization of

H NMR is used to identify the unknown aldehyde and ketone. Melting point is used to identify the aldol condensation reaction. Theory: Condensation reaction is also known as a dehydration reaction. In the mechanism of condensation reaction‚ a bond is formed between two molecules and creates water as a
