Stoichiometry Of Baking Soda And Sodium Hydrogen Carbonate

1477 Words6 Pages

Background:

The study of stoichiometry is a branch off Chemistry its the study of the amounts of substances that are involved in reactions. For this experiment kinetics is a huge part of it. Kinetics is explained as the reaction speed and or rate of reaction. To observe these reactions made by having reactants, sodium hydrogen carbonate, NaHCO3 known as baking soda and acetic acid, CH3COOH that is vinegar being mixed together. The products were carbon dioxide, water, and sodium acetate. Because this reaction will be based on its speed according to the difference in temperature, the higher the temperature the faster the reaction will occur creating a direct relationship. The balanced equation is as follows:

NaHCO3 (aq)+ CH3COOH (aq) → …show more content…

Once it is set, acquire a weigh boat and add 4.2 grams of baking soda to the weigh boat. After doing so repeat steps 1 and 2, four more times, which would mean five weigh boats of 4.2 grams of baking soda. Once that is completed, place the weigh boats somewhere safe and move on to part 2.

Part 2: Preparing the Acetic acid Wash the 100mL-graduated cylinder and dry it with paper towels. Then get the Acetic acid and pour exactly 100mL of it into the graduated cylinder (This should almost fill it up). When that is completed repeat steps 1 and 2 four more times, which would mean five graduated cylinders of 100mL of Acetic acid.

Part 3: Carrying out the reaction Wash the 250mL-beaker and dry it with paper towels. Add one of the 4.2 grams of catalyst (Sodium Hydrogen Carbonate) that has been obtained in step one into the beaker. Making sure that the beaker is dry before hand. Get the stopwatch ready to record the time of the reaction. Apply one of the 100mL Acetic acid into the beaker and start the stopwatch as soon as the two substances meet. Record the qualitative data observed in the

Stoichiometry Lab

563 Words | 3 Pages

Stoichiometry is a method used in chemistry that involves using relationships between reactants and products in a chemical reaction, to determine a desired quantitative data. The purpose of the lab was to devise a method to determine the percent composition of NaHCO3 in an unknown mixture of compounds NaHCO3 and Na2CO. Heating the mixture of these two compounds will cause a decomposition reaction. Solid NaHCO3 chemically decomposes into gaseous carbon dioxide and water, via the following reaction: 2NaHCO3(s) Na2CO3(s) + H2O(g) + CO2(g). The decomposition reaction was performed in a crucible and heated with a Bunsen burner.

Verna Wang Hannah Palmer CHEM 101-069 Lab 11-19-16 Stoichiometry and Limiting Reagents Lab Report Purpose: We are using the reaction of sodium hydroxide and calcium chloride to illustrate stoichiometry by demonstrating proportions needed to cause a reaction to take place. Background: Just like a recipe would call for a specific amount of one ingredient to a specific amount of another, stoichiometry is the same exact method for calculating moles in a chemical reaction. Sometimes, we may not have enough of or too much of one ingredient , which would be defined as limiting and excess reagent, respectively.

To determine the rate of reaction there are many method to be used for example, measuring the mass after the product has been added and measuring the difference in mass on the duration of a digital scale. Another method, which will be used in this experiment is using a gas syringe to measure the volume of the gas which has been produced. The cylinder inside, will be pushed out to show a quantitative presentation of the volume produced by the reaction. Hypothesis

The Effect of Sugar Concentration on CO2 Production by Cellular Respiration in Yeast Introduction In this lab, our main focus was to find how sugar concentration affect yeast respiration rates. This was to simulate the process of cellular respiration. Cellular respiration is the process that cells use to transfer energy from the organic molecules in food to ATP (Adenosine Tri-Phosphate). Glucose, CO2, and yeast (used as a catalyst in this experiment) are a few of the many vital components that contribute to cellular respiration.

CH3COOH And Naoh Lab Report

1052 Words | 5 Pages

Introduction Strong acids and strong acids both dissociate completely in water forming ions. However, strong acids donate a proton to form H3O+ along with a conjugate base and strong bases accept a proton to form OH- along with a conjugate acid. The chemical behavior of acids and bases are opposite. When they are together, their ions cancel out and form a neutral solution. In this experiment, HCl and NaOH will react to form NaOH and H2O with these two steps: The overall reaction is: Both Na+ and Cl- ions combine to form NaCl.
