OBJECTIVE:
The purpose of this lab is to determine the percentage yield of the reaction between sodium bicarbonate and acetic acid.

INTRODUCTION
This lab demonstrates the double replacement / acid-base neutralization reaction between the reactants of two household cooking items, baking soda and vinegar, producing carbon dioxide, water, and sodium acetate.
Baking soda is an odorless, powdered chemical compound called sodium bicarbonate (NaHCOз). NaHCOз is most commonly used in baking as a leavening agent, along with acidic components like vinegar, also used as a reactant in this lab. Sodium bicarbonate melts at 60°C, and does not have a boiling point, but it decomposes at temperatures over 70°C. When reacted with an acid, it evolves carbon dioxide. Vinegar is a colourless substance that contains acetic acid (CHзCOOH). Regular household white vinegar is not pure acetic acid, and usually contains about 5% of acetic acid. Pure acetic acid boils at around 117.9 °C, melts at 16.6 °C, and is completely miscible with water, but household vinegar boils at around 100.6°C. …show more content…
These 2 reactants react to form carbon dioxide, water, and sodium acetate as shown in the chemical reaction below:

    Alka-Seltzer Co: Two Gases

    After the reaction, and an incision to release the gas, the mass also had to be identified, which was less than the previous mass, 255.9 grams. The experimental molar mass was 0.0894 grams, found by using the moles of 〖Co〗_2 and the masses. The percent yield came about by dividing the experimental molar mass by the theoretical (44.01grams) to create 20 percent. The percent yield shows how far off the experimental calculations were from the truth. Overall, by using the Alka-Seltzer, what could be concluded was that Alka-Seltzer reacts…

    Two of Alka Seltzer’s ingredients, Citric Acid and Sodium Bicarbonate (Baking Soda), were both placed into a beaker to see if both contents could cause a potential reaction. The final result was a non- occurring reaction. For a second test, both the Citric Acid and Sodium Bicarbonate were placed into separate, dry beakers.…

    When hydrochloric acid was added to the unknown and known solutions, both resulted in no reaction. This also occurred when potassium hydroxide was added to both of the solutions. Barium chloride was then added to the two solutions, which resulted in a cloudy white precipitate from both of the solutions. A cloudy white precipitate also formed when calcium nitrate and ammonium nitrate were added to both the unknown and known solutions. These reactivity tests were conducted in order to establish how the unknown compound would react with acids, bases, and salts.…

    Describe Acid-Base Synthesis

    Because the percentage of each compound in the mixture was not given, both the percent yield calculated and yield will contain both the unknown acid and the neutral compound. Since the product from the organic layer was never recrystallized, the impurities in it may have caused the percent yield to be greater than 100%. 12. The melting point range of the unknown acid was 109-116 °C, while the mixed melting point range of the unknown acid with 2-chlorobenzoic acid was 119-124 °C. These two ranges are very close to each other, and the latter range is narrow compared to the other mixed melting points, so it makes sense that 2-chlorobenzoic acid is the unknown acid.…

    Baking Sod Rough Draft Body

    Soda ash contains sodium, carbon, and oxygen (Sideman). Then, the soda ash turns into water and carbon dioxide (Sideman). This is the basic way of making soda ash, which is needed to make baking soda, but to see more details, history needs to be looked at (Sideman).In late 1800’s, a Belgian man named Ernest Solvay created a different process of making soda ash, which is now used today (Sideman). He made a mixture of carbon dioxide and ammonia (NH3) and put the mixture into a concentration solution of sodium chloride (Sideman). As a result, sodium carbonate formed and was heated; this heating formed soda ash (Sideman).…

    Sodium Bicarbonate Essay

    I had also identified the correlation between Sodium bicarbonate and the unknown substance in terms of how they both react with water (neither of them dissolve in the water, rather is more dense than the water which seemingly causes the Sodium bicarbonate or Unknown substance to sink to the bottom of the platform. The Sodium bicarbonate and Unknown substance had reacted alike when they make contact with acidic acid. Being that they become extremely reactive with the acidic acid, forming consecutively larger bubbles until the solute (being Sodium bicarbonate) had completely dissolved in the acidic acid. Using the universal indicator it can be observed that the Unknown substance or Sodium bicarbonate had both became a chunky paste, which turns into a dark green colour which signifies that it is a moderately neutral-weak acid. Finally, when comparing the Unknown substance and the other substances that had been listed, I had found that Sodium bicarbonate had proudly fitted the results like those of the Unknown substance’s, those results being, they had both dissolved quite well into the iodine solution and later became a viscose, dense, and rather lavish orange colour.…

    Baking Soda Vs Vinegar Acid

    In the chemical reaction baking soda and vinegar, many different things are happening. When baking soda is added to vinegar almost instantaneously the reaction starts. One of the first observations a white foaming substance. This occurs because one of the products CO2(g) is releasing causing bubbles to form. Once the reaction settles a clear-ish liquid can be seen the products that are left behind to form this liquid are H2O+NaCH3COO(aq).…

    Baking Soda and Vinegar Rockets Introduction: Baking soda and vinegar are both compounds that can go off at any moment when it is applied. We had to see what would happen is we added 10mL of vinegar in the canister and see what amount of baking soda could make the canister go the furthers. We found out that this whole turning baking soda and vinegar to a rocket was going to be a chemical change. The chemical name for baking soda is (NaHCO3) and the chemical name for vinegar is (CH3COOH) and both of these elements are compound.…

    Discussion: The hypothesis stated that as the amount of baking soda increases, the total time of its reaction with vinegar will be increased as well. However, that was not the case during the actual experiment. As discussed previously, the results followed a small pattern but not for the whole experiment. The results can be confirmed that are very reliable, since repeated trials were done, sometimes more than three.…
