Abstract: The purpose of this experiment was to identify given Unknown White Compound by conducting various test and learning how to use lab techniques. Tests that are used during this experiment were a flame test, ion test, pH test, and conductivity test. The results drawn from these tests confirmed the identity of the Unknown White Compound to be sodium acetate (NaC2H3O2) because there were no presence of ions and sodium has a strong persistent orange color. The compound then will be synthesized with the compounds Na2CO3 and HC2H3O2 to find percent yield.
Alka-Seltzer is a medical drug that works as a pain reliever and an antacid. The pain reliever used is aspirin and the antacid used is baking soda. When sodium bicarbonate dissolves in water it splits apart into sodium and bicarbonate ions. The bicarbonates reacts with hydrogen ions from citric acid to form carbon dioxide gas and water. This is how the bubbles are made.
List the various types of baked products they are used in, describing there effect on the individual products. Malt Flour: This type of flour is a special ingredient for bread makers as it promotes a strong rise, a lovely texture and a brown crust which makes the product more desirable. The active enzymes in the flour make sure that during fermentation the products grows effectively and have a good oven spring. It also helps the bread stay fresher.
Introduction Alka-Seltzer has been on the market since 1931 and has helped to relieve indigestion and upset stomach. The tablets began to fizz and bubble when dropped into water. “The fizziness happens when baking soda (sodium bicarbonate) and citric acid react chemically in water. They yield sodium citrate, water and carbon dioxide gas, which causes bubbles.” Based on this information, we will measure the reaction time of AlKa- Seltzer dissolved in 200 ml of water at 3 different tempertures in the first portion of this experiment.
Sodium Bicarbonate mixed with Hydrochloric acid. The chemical reaction observed showed that there was fizzing and bubbling, this is evidence that a new gas was being produced. This new gas, CO2 was generated from the reaction. After the fizzing stopped a liquid was leftover leading me to conclude the liquid leftover leading me to conclude the liquid leftover was the NaCl and H2O 4. You found a sample of a solution that has a faint odor resembling vinegar (an acid).
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.
Once hydrogen and the baking soda ions bump into each other, they form carbonic acid (H2CO3). Carbonic acid decays to form carbon dioxide and water. The formation of the carbon dioxide causes the fizzing action seen in the experiment. It is shown in the equation: H+ (aq) + HCO3 - (aq)
Introduction: The purpose of this experiment is to demonstrate the different types of chemical reactions, those including Copper. There are different types of chemical reactions. A double displacement reaction is a chemical process involving the exchange of bonds between two reacting chemical species. A a decomposition reaction is the separation of a chemical compound into elements or simpler compounds and the single-displacement reaction is a type of
H2CO3 The popping sound we hear when we open the can of fizzy drink, the bubbles and sparkle we see in the soft drink, and the feeling of bubble popping on your tongue, all of these are due to carbon dioxide escaping from solution. One of the reasons people love to drink
How does the amount of baking soda mixed with vinegar affect the volume of gas produced per 10 seconds? A reaction is when (usually) a solute acts on a solvent to create a reaction. An example of a reaction is an explosion, Here we will be using baking soda and vinegar which are our two components which will cause for a reaction to take place. Reactions can be affected by several things such as temperature, concentration and the presence or absence of a catalyst which is a substance which can increase the rate of reaction.
Everyone knows the simple and easy experiment of vinegar and baking soda, but do you really know how it works. This paper will not only explain what makes these two very different chemicals react, but also what materials you will need to accomplish this easy science experiment. Baking soda and vinegar are two different chemical with two very different uses, they are not really even supposed to be used for a science experiment, take vinegar for example, some individuals use vinegar for cooking. Baking soda has a very different use, it is used for bee-stings. When vinegar and baking soda are combined, the hydrogen ions in the vinegar interact with the sodium and bicarbonate in the baking soda.
Then the balloon is lifted up so that the baking soda runs into bottle to react with the vinegar inside. Immediately the balloon is inflated by the carbon dioxide formed. The baking soda is kept constant when the experiment is repeated for another different amount of vinegar. Results/Findings When sodium bicarbonate and vinegar mix,
The other for dissolving the baking soda later. Then you will also need to get your utensils and cooking pans such as spatulas, oven, oven mitts, mixer,teaspoons and measuring cups. The
What is the effect of temperatures 10°C , 20°C, 40°C, 60°C and 70°C ± 1/°C on yeast fermentation when baking bread? ii. Aim: The focal aim of this experiment is to investigate the effect that temperature has on the growth and respiration of yeast (Saccharomyces cerevisiae) fermentation. iii.
CONCLUSION When you put an egg in vinegar, we see that the shell dissolves, but do you ever wonder why? An egg is made mostly out of calcium carbonate which reacts with an ingredient in vinegar, acetic acid. Acetic acid is about 4% of the vinegar and what breaks apart the solid calcium carbonate crystals. The bubbles we see, from the egg, is the carbonate that make carbon dioxide and the other calcium ions float free. This is the equation: CaCO3 (s) + 2 HC2H3O2 (aq)
