When baking soda is combined with moisture and an acidic ingredient, the resulting chemical reaction produces bubbles of carbon dioxide that expand under oven temperatures, causing baked goods to rise. Baking powder contains sodium bicarbonate, but it includes the acidifying agent already (cream of tartar), and also a drying agent (usually starch). The ultimate goal is to produce a tasty product with a pleasing texture. Baking soda is basic and will yield a bitter taste unless countered by the acidity of another ingredient, such as buttermilk. Cookie recipes typically include baking
Quality Control for Athenium Baking Soda Company Introduction In this experiment, we will be using thermal gravimetric analysis (experiment 4) and HCL titration (experiment 12) to determine the percentage of NaHCO3 (baking soda) in the sample given. We will also be using emission analysis for group IA and IIA salts (experiment 10) to determine the impurities present. The purpose of this experiment is to determine the purity of a sample of baking soda given us by the Athenium Baking Soda Company. We will First determine the percentage of baking soda and then determine whether it contains particulates of CaCl2, LiCl, of KCl for the purpose of seeing whether it is pure and useable or not (the quality of the baking soda). We are performing the experiment to gain our spots on the team of quality control for the Athenium Baking Soda Company.
Quality Control for the Athenium Baking Soda Company April 16, 2012 Introduction: In a sample of baking soda, determine the percent by mass of NaHCO3. Also, determine if any chemical impurities are present, the chemical nature of the impurities, and the quantity of each present. Baking soda, also known as sodium hydrogen carbonate or sodium bicarbonate (NaHCO3), is a naturally occurring compound with a wide range of uses. The diverse uses of baking soda include its presence in cleaning products, human food and beverages, animal food, and food processing, pharmaceuticals, chemical and industrial processes, water treatment, fire extinguishers, and more (chemicalland21). Because baking soda is a natural compound, using it in these products can replace potentially environmentally harmful products.
Quality Control for the Athenium Baking Soda Company A Self-Directed Experiment 16 April 2012 INTRODUCTION The Athenium Baking Soda Company has begun producing baking soda (sodium bicarbonate, or sodium hydrogen carbonate). NH4HCO3 + NaCl ==> NaHCO3 + NH4Cl Due to the high concentration of the brine solution that is used to generate the product, contaminants are often present in the finished product as chloride compounds. The contaminants may be detected when the finished baking soda product is dried and filtered. PURPOSE: In this experiment, we will be employing quality control by analyzing the composition and purity of the contaminated baking soda samples. To perform this experiment, we will utilize emission spectra, titrations, and thermal gravimetric analysis, using knowledge from Experiments 10, 4, Titrations of Na2CO3 and NAHCO3 by HCl (hydrochloric acid) will be performed to determine the concentration of HCl, as well as the number of moles of HCl present within the sample of baking soda.
In order to ensure quality control for the Athenium Baking Soda Company’s product, we will select three methods of experimentation to determine the purity of its baking soda, as well as its composition. The first experimental procedure to take place will be a thermal gravimetric analysis, which will help determine the percent composition of sodium bicarbonate of a sample of the company’s baking soda. In this experiment, a known mass of a sample of the company’s baking soda will be added to a crucible and heated until it decomposes into solid sodium carbonate, gaseous carbon dioxide, and gaseous water, as shown in the following equation: 2NaHCO3(s) Na2CO3(s) + CO2(g) + H2O(g) After a reheating of the crucible to ensure accuracy, the stoichiometric ratio for the mass loss of CO2 and H2O per gram of NaHCO3 will be determined, along with the total mass of CO2 and H2O lost upon heating. These will be used in order to determine 3 the mass of NaHCO3 present in the sample. Finally, using the collected data, the percent by mass of NaHCO3 in the company’s
Then by writing a balanced chemical equation and using the titration formula, Nb+Ma+Va=Na+MbVb , the molarity is able to be determined. Procedure: 1) Using the graduated cylinder add 10.0 mL of water into the Erlenmeyer flask. 2) Add 5.0 mL of HCl into the flask using another graduated cylinder because acid goes into water when mixing them. 3) Add three drops of phenolphthalein indicator into the flask. 4) Swirl the flask in circular movements to mix the substances.
Just let this mixture stand 5 to 10 minutes before using. The cake batter uses the creaming method, that is, beat the butter with the sugar until creamy, add the egg and vanilla extract, and then alternately add the flour mixture and buttermilk (mixed with the liquid red food dye). The final step is to add a mixture of baking soda and vinegar. Because baking soda starts to react with the batter right away, try to get the cupcakes into the oven as quickly as possible. Finally, the frosting, which is really what cupcakes are all about.
Rates of Reaction - Marble Chips and HCl In this experiment, marble chips, or Calcium Carbonate (CaCO3), will be dropped into a flask containing Hydrochloric Acid (HCl). The reaction is: CaCO3(s) + 2HCl(l) --> CaCl2 + H2O(l) + CO2(g) The experiment will determine whether or not stirring quickens the reaction rate, which will be illustrated by the slope of the lines in the data graph. If heat and stirring is added to a reaction, then the gas will be released quicker. This is so because when two compounds interact, or collide, a reaction occurs. If the compounds are made to collide faster, by way of stirring, then theoretically the reaction as a whole will start faster and come to completion faster.
Title : Reaction of Carboxylic Acids Objective : To Determine The Reaction of Carboxylic Acids Procedure : As referred to Lab manual. Results: A. Salt Formation |Compound |Solvent |Solubility | |Benzoic Acid |Cold Water |Partially soluble | |Benzoic Acid |10 % NaOH |Soluble | B. Salt Hydrolysis Sodium acetate solution changed the color of litmus from red to blue. C. Reaction With Sodium Carbonate Observation : A lot of gas bubbles was released.
The pipette was then filled with 25.0mL’s of acetic acid and then drained into a conical flask, to speed up the process both of the conical flasks were filled with 25.0mL of the acetic acid. 8. Three drops of phenolphthalein was then added to the flask with the acetic acid. 9. The conical flask was then positioned to just under the burettes dropper which had its stopcock opened to allow a medium drip rate and had the sheet of filter paper slipped under it so that the colour could be seen more earily.
