This experiment is designed to demonstrate two concepts. First, it will provide a demonstration of how chemists can use chemical reactions to understand reaction mechanisms. Second, is the concept of multi-step synthesis. You will be performing the following reaction: Isomer IIsomer II + Enantiomer+ Enantiomer Brominetrans-Cinnamic Acid2,3-Dibromo-3-phenylpropanoic acid MW 160 g/molMW 148 g/molMW 308 g/mol […]
Ferrocene was acetylated in acetic anhydride and phosphoric acid. It proceeded via a Friedel-Crafts reaction without the use of organic solvents or strong Lewis acid. Operations and Observations A mixture of ferrocene (1. 5 g, 0. 008 mol), acetic anhydride (5 mL) and phosphoric acid (1 mL 85%) was heated over a steam bath until […]
I am going to do an investigation into the ethanoic acid content of various kinds of vinegar. The chemical equation for the making of ethanoic acid is as follows: ethanol oxidization bacteria Ethanoic Acid To do this experiment I intend to do an accurate titration using a burette. Hypothesis: I predict that the amount of […]
Aim and Hypothesis: My aim in this experiment is to compare the enthalpy change of neutralisation by titration, for each reaction between the following 3 acids:Sodium hydroxide (NaOH) and hydrochloric acid (HCl) – pH 1Sulphuric acid (H2SO4) and NaOH – pH 1NaOH and Ethanoic acid (CH3COOH) – pH 2.88 – 3I predict the reaction between […]
Aim: The aim of this investigation is to discover if different variables affect the rate of diffusion. My aim is to discover if the concentration of the acid affects the rate of diffusion. Preliminary Work: For my preliminary work I looked at different types of diffusion. First I sprayed an air freshener across the classroom, […]
Sulfuric acid also has a low volatility. Disadvantages: Sulfa Acid can be an Irritant to eyes or skin and Is the most expensive of the De- scalars. Q) How these De-scalars remove Eliminates Lamellar forms when hard water Is heated above 61 co or when go fd’pgJ’dsfpkj gaffing ‘depressing dogfish gpofdsjg’ksdfJg footpads 1 Research What […]
The determination of calcium carbonate present in the Eggshells. Introduction: The Major component of eggshells is calcium carbonate (CaCO3). This analysis will be done volumetrically by using a characteristic reaction of carbonate compounds, namely their reaction with acids. Calcium carbonate (limestone) is very insoluble in pure water but will readily dissolve in acid according to […]
Investigating Membrane Permeability Reason for choosing beetroot as the object of experiments Beetroot is usually used as the membrane ādisruptionā experiment. It is because of beetroot has more pigments in their vacuole. These pigments show how variables damage the membrane of beetroot. The pigments will be automatically extracted from the vacuole when the membrane is […]
A balanced equation of the reaction:Ca(OH)2(aq) + 2HCl (aq) CaCl2(s) + 2H2O(l)The aim of my experiment is to determine the concentration of a limewater solution which contains approximately 1g dm-3 of calcium hydroxide by using hydrochloric acid as a reagent in a titration.Safety ProceduresThe following safety procedures should be notified first to ensure the safety […]
Indigestion is a general term used to describe discomfort or pain in the upper abdomen or chest, which is sometimes experienced while our bodies digest the food we eat. A better and more scientific term for indigestion is dyspepsia. Indigestion is caused by too much acid in the stomach. Indigestion tablets contain bases, which neutralize […]
Hi. I am Gold. I have been around since the beginning of time, but humans started to use me only 4000 years ago. Now, don’t think that you can throw me out into the garbage; there are millions of people who will come looking for me. Firstly, I am one of the most expensive and […]
The word and chemical equation which I have constructed for the experiment is:Calcium + hydrochloric calcium + water + carbonCarbonate acid chloride dioxide.CaCo3 + 2HCL CaCl2 + H2 O + CO2Reactant ProductI chose this reaction because it is easy to control as the production of carbon dioxide being produced can be monitored with ease. Additionally […]
One of the more common reactions seen in chemistry is the acid/base reaction. The most common result of an acid/base reaction is the formation of water and a salt. Such a reaction can be highly useful in the analysis of an unknown acid or base. By titrating the unknown analyte with a standard reagent, several […]
Metal Zinc Blobbing Magnesium Fizzing Bubbling Iron Copper Reactions with Indicators Speed of Reactions With Metals Observations continued: In my observations, in data table 1, the only solution that reacted with the red litmus paper was Noah. All three solutions reacted with the blue litmus paper; HCI and HACHURE turned the blue litmus paper red, […]
When sodium bicarbonate and clerk acid mix In water they dissolve, the sodium bicarbonate reacts with the clerk acid to form sodium citrate and carbon dioxide. The carbon dioxide then bubbles out as a gas, which makes the bath bomb break up, In this experiment 3 tests will be conducted In order to find the […]
An investigation into the total acid content of assorted brands of lemon and lime soft drink Abstract: The aim of this experiment was to determine the total levels of carbonic acid concentration in 3 differing brands of lemon and Lime soft drinks. Research Question: Does the acid content in three different lemon and lime flavored […]
Abstract: The aim of the experimental investigation was to gather four dissimilar water samples and test them in several different methods to see which water sample had the best quality. The tests that were used were that of: A fecal chloroforms test, phosphate test, nitrates test, pH test, dissolved oxygen test and a total dissolved […]
Aim: To calculate the enthalpy change of naturalization of the given pairs of acid and base. Theory: When alkali neutralizes an acid. A salt and water are formed. Aqueous hydrogen Ions, from the acid react with the hydroxide ions, OH-(as) from the alkali, forming water. Ionic equation: H+ (as)+OH- (as) -9 H2O (l) The Identity […]
Experiment Four: Organic Synthesis of Aspirin Abstract The purpose of this experiment is to synthesize a common organic product called ecstatically acid (aspirin), and to become familiar with the optimum conditions needed for successful yields. Aspirin is produced from an acid catcalled reaction between salicylic acid with acetic anhydride. The crystalline aspirin Is synthesized and […]
Abstracter is important substance for all living organisms. The physical and chemical properties of water play a central role in biological structure and function of the organism. The nomination ability of water to form H+ and OH- ions make it very unique. The hydrogen-ion concentration of biological system is usually preferred as the pH system, […]
The type of acid being investigated is monophonic and the reaction equation between ascorbic acid and sodium hydroxide is unknown. The name and structure of the conjugate base of ascorbic acid is acerbate, with the structure CHICHI-. This investigation focuses on the redo properties of ascorbic acid, including the structure of its oxidized form, Dehydration’s […]
Phenolphthalein is another acid-base indicator. What color do you observe? (General College Chemistry, 2014, up. 17-18). G. HCI and phenolphthalein. What color do you observe?
