Baking Soda And Vinegar Lab Report

1. Record your hypothesis about what will happen when Biuret solution is mixed with the solutions from test tubes 1, 2, 3, and 4 here. Be sure to use scientific reasoning to support your hypothesis.

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 using the 6.56g of baking soda and 26mL of Hydrochloric acid the bag inflated too quickly and too much and the bag popped and released all the gas through the top. Our third and final trial of 5.15g of baking soda and 20mL of Hydrochloric acid the bag inflated in about one second and inflated to just the right amount where the bag was not too hard and not too soft.

A mixture, unlike a compound, can be separated by physical means. There are multiple ways in which a mixture can be separated; furthermore, the ways it can be separated is based on what the mixture is made up of.

First students obtained 8 graduated cylinders and labeled them. Each one contained a different ratio of vinegar and water. These graduated cylinders with the liquid were weighed and recorded.Then, students obtained an Alka-Seltzer tablet and recorded its mass. Then one alka-seltzer tablet was dropped into each of the graduated cylinders. Students had to

The objective of this experiment will be to combine various substances, liquids and metals, and to observe their behavior when they are combined. The types of reactions observed shall determine the nature of these reactions: physical or chemical.

Alka-seltzer Lab Report Statement of the Problem: The question of this lab was to find the optimum amount of Alka-Seltzer and water to achieve the highest launch possible. As Alka-Seltzer can dissolve in H2O and release CO2g (carbon dioxide gas), the gas is trapped inside the container and starts to gain pressure. This is the combination produces Sodium Bicarbonate which releases CO2g and other products. When the pressure in the container reaches maximum pressure, the lid will pop off releasing the gas and making it fly upwards.

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.

The limiting reactant of a chemical reaction is the substance that places an upper bound on the amount of product that the reaction can produce. The limiting reactant places this upper bound because the reaction must stop once all of the limiting reactant is consumed.

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

The purpose of this experiment was to see if altering the ingredients of a bath bomb affected the effervescent when placed in water. When a bath bomb is submerged in water the ingredients caused it to fizz, releasing a scent and changing the color of the water. This bath bomb experiment requires two recipes, the first recipe which was labelled as “normal”, contained less cornstarch than the other recipe. In addition to the “normal” recipe, the other recipe was labelled “extra” because it contains more cornstarch. During this process, by adding or subtracting ingredients the eversences of the bath bomb changed. If more cornstarch is added to the recipe, the bath bomb will not fizz as much when placed in water. This is caused by the cornstarch,

4.) Using a different spatula, place a similar amount of baking soda in wells D,E and F. Again, recording any physical observations you observe.

People have wondered for a long time, why do Mentos and coke have a huge reaction. People do experiments on it and test it or they just do it for fun. Some people make little cars and test the experiment on them, seeing how far a car will go if it was propelled by the soda and Mentos. But first, if they want to test the soda and Mentos powered car, they might want to know a couple things about the reaction and some things that can help their car go faster or they need to know the laws of motion or the pressure in the soda and Mentos.

The soda ash form experiment 3 was obtained. A 250 ml beaker was obtained and rinsed.

My experiment is divided into two parts; experiment A (involving the relationship between flexion and the mass of the load) and experiment B (involving the relationship between the flexion and the length of the cantilever).
