Baking Soda Experiment

If the 0.2 g, 0.4 g, 0.6 g, 0.8 g, or 1 g (±0.1) of baking soda used in this experiment increases, then the volume (mL) (±0.5) of the carbon dioxide released from the decomposition will also increase.

When combined Sodium Bicarbonate and Hydrochloric Acid, Carbon Dioxide is produced. The two chemicals do not undergo a change in color but a chemical change when CO2 is produced.

The mixture of sodium bicarbonate and sodium carbonate can be separated due to the different temperatures at which the carbonate and bicarbonate decompose. This separation is the focus of the experiment. The bicarbonate decomposes when heated by the Bunsen burner. The carbonate also will decompose but at a much higher temperature. So, when the bicarbonate is heated it decomposes into carbonate, and during the decomposition it releases water and carbon dioxide. Furthermore, the amount of water and carbon dioxide released can be found by finding the difference in mass of the original mixture (before heating) and the final mixture (after heating). The mass of the water and carbon dioxide can be used to find the percent composition of bicarbonate in the mixture.

“when water underground comes in contact with a source of carbon, such as limestone” (sciencebuddies.org) soda pop is a sweet tasty thing for the taste buds and even though it’s not the best for people scientist believe it is good for your taste buds and throat because its cold and soothing that’s why if one is sick or have a upset stomach certain soda will make one feel better. Because of the fizz in it and coolness it will

By adding acid to the baking soda, it caused the substance to form bubbles and release gas. More drops of HCl were added until the bubbling

A chemical change can be caused by combining two compounds, such as baking soda (NaHCO3) and vinegar (CH3COOH). The change that is taking place is because of the chemical property of reactivity. When these two compounds react CO2 is produced. In this experiment we wanted to see how much baking soda, added to 10mL of vinegar, would cause a film canister rocket to shoot the farthest. I predicted that 10mL of baking soda would shoot the farthest because it would be equal to the amount of vinegar in the canister. The independent variable in this experiment was the amount of baking soda and the dependent variable was how far the lid would shoot.

9.Repeat the procedure with a new mass of baking soda. Before beginning, rinse the reaction vessel with water. Refill the graduated cylinder with water. Check water level in collection box so it has room for the water from the graduated cylinder.

Removed balloon from bottle after reaction and tied the end. Measured the mass of tied balloon on digital scale in grams. Calculated the mass of carbon dioxide in the balloon (actual yield) in grams(g). mass of 〖CO〗_2=mass of balloon after reaction-inital mass of balloon Created ratios of moles of CO2 to CH3COOH and CO2 to NaHCO3.

From the results that were acquired from mixing the liquid reagents with each powder, it was determined that Unknown Mixture #1 consisted of baking soda and cornstarch. When individually testing the substances from Unknown Mixture #1 with the liquid reagents, a few noticeable reactions occurred. Mixing baking soda with vinegar caused bubbling to occur. This is because a neutralization reaction took place between the two reactants. In this reaction, sodium bicarbonate(baking soda) reacts with vinegar and produces sodium acetate, water, and carbon dioxide(HC2H3O2(aq) + NaHCO3(aq) NaC2H3O2(aq) + H2O(l) + CO2(g) ). The gaseous carbon dioxide most likely tried to escape into the atmosphere and caused the bubbling to occur. Another noticeable reaction

In conclusion, the more baking that was added in the reaction the more gas that was produced. When there was only one scoop of baking soda, the least amount of gas was produced, when three scoops of baking soda were used, the most amount of gas was produced. The number of bubbles roughly stayed the same, so the number of bubbles created was not affected by the amount of baking soda. With increments of 1 scoop of baking soda, small amounts of gas are produced each trial. We compared each trial by identifying the firmness of the bag due to the gas. Since gas takes up space of the bag, the more firm the bag is, the more gas is produced. Therefore, our hypothesis of having more baking soda will make more gas is correct.

When handling acids and bases, caution, such as wearing safety glasses and avoiding the direct smell of chemicals must be implied. The next step involves the reactions of metals with air, metal oxide and water, and acid. Firstly, a copper strip will be held in the flame of a candle for a few minutes. After heating, the burnt coating of the copper strip will be scraped off to differentiate how the copper appeared before and after. In the next reaction, calcium oxide will be mixed with two inches of distilled water, followed by two drops of phenolphthalein.

When mixed with a variety of liquids, each substance reacted differently. For example, only baking soda reacted with a chemical change when mixed with vinegar. It fizzed when they both mixed. A physical change happened when the powders were mixed with water. When baking soda was mixed with iodine, it created a physical change because it did not make the iodine change to an unexpected color, it stayed yellow.

When you mix baking soda and vinegar you get a chemical reaction called reactivity. When your chemical reaction occurs you usually get a change in color, an odor, and a production of gas. Baking soda is a compound (NaHCO3) and vinegar is also a compound (CH3COOH). The problem was how much baking soda, added to 10mLof vinegar, will cause a film canister rocket to shoot the furthest? My hypothesis was that 15mL of baking soda would shoot the lid the furthest because it’s the highest number I would have put into the canister. The dependent variable is the film canister with the vinegar inside and how far the lid shoots. The independent variable

Oxygen is produced when manganese dioxide and hydrogen peroxide are mixed together. When manganese oxide is added to hydrogen peroxide bubbles of oxygen are given off. I know this because flames need oxygen to burn and when the flame was introduced to the gas it got brighter and larger. D. Carbon dioxide gas is produced when hydrochloric acid and baking soda are mixed together. I know this because carbon dioxide will extinguish the flame and in both my burning and glowing splint tests the flame was extinguished.

The mixing of vinegar and baking soda causes a chemical reaction. The mixture of baking soda and vinegar caused a chemical reaction, thus inflating the balloon. Five ml of baking soda and vinegar was added into the flask and balloon. The initial temperature is -25 °C. The final temperature is -23 °C.
