Although people enjoy bath bombs, many people are allergic to some of the main ingredients in them. The objective in this experiment is to find alternatives to some of these main ingredients and to find the ingredient that causes the bath bomb to fizz the most and the fastest. Our hypothesis states that if the cornstarch, lemon juice, and cream of tartar bath bombs are compared to citric acid bath bombs by measuring the temperature change of water when they react, then lemon juice bath bombs will react most like the citric acid bath bombs, and temperature of the water will drop two degrees. To complete the experiment, we took the twelve bath bombs out of their molds, measured the mass of the plastic cups, put one bath bomb in the plastic cup …show more content…
Although people enjoy them, many people are allergic to some of the main ingredients in bath bombs. The objective is to find alternatives to some of these main ingredients and to find the ingredient that causes the bath bomb to fizz the most and the fastest. The different ingredients were lemon juice, cornstarch, and cream of tartar. In each bath bomb, baking soda, sodium bicarbonate, was used. Baking soda is used because of its alkaline properties and based on each ingredient, it will react differently (“Sodium Bicarbonate” Hyperphysics). Citric acid is a white solid crystal found in fruits such as oranges, lemons, etc. When baking soda and citric acid combine, a reaction occurs, and once this mixture touches water, it fizzes, pops, and creates bubbles. The chemical equation for this reaction is C6H8O7+ 3NaHCO3 -> CO2 + H2O + CH3COONa. The formation of bubbles is from the carbon dioxide released from the reaction (“Fizzy Sherbert”). Lemon juice, commonly using for its cleaning properties, was another alternative ingredient. When lemon juice and baking soda combine, it causes a chemical reaction. Once they combine, they begin to fizz due to the carbon dioxide being released (Rogers, “Lemon Fizz”). Another alternative was cream of tartar because of the fact that it reacts well with baking soda. When the two react and are put in water, new molecules form such as …show more content…
Then, we took the twelve bath bombs out of the molds. There were four different kinds: citric acid, lemon juice, cornstarch, and cream of tartar. Three bath bombs of each of the four kinds to have three trials to ensure the consistency of the experiment. 1000 mL of room temperature tap water was put into a 2000 mL container that was used to allow the bath bombs to react. We plugged in the balance and zeroed it. We then placed an empty plastic cup on the balance to calculate its mass. Once calculated, the balance was tarred and the lemon juice bath bomb was placed in the plastic cup and the mass of each was recorded. Before putting a bath bomb into the water, the temperature of the water was taken using a temperature probe and that temperature was recorded. Then the bath bomb was placed in the water for a total of one hundred seconds. The temperature of the water was recorded in ten second intervals, zero to one hundred, as the reaction of each kind of bath bomb was taking place. Observations were recorded before, during, and after the reaction was completed. Once the one hundred seconds were over, the water was poured out, and the container of water was cleaned. For each type of bath bomb, we made sure each had the same mass before being tested. This process was repeated for each of the following bath bombs, and a new cup was used for each new bath bomb. Once all of the data was collected and recorded for
First, 100 mL of regular deionized water was measured using a 100 mL graduated cylinder. This water was then poured into the styrofoam cup that will be used to gather the hot water later. The water level was then marked using a pen on the inside of the cup. The water was then dumped out, and the cup was dried. Next, 100 mL of regular deionized water was measured using a 100 mL graduated cylinder, and the fish tank thermometer was placed in the water. Once the temperature was stabilizing in the graduated cylinder, the marked styrofoam cup was filled to the mark with hot water. Quickly, the temperature of the regular water was recorded immediately before it was poured into the styrofoam cup. The regular/hot water was mixed for a couple seconds, and the fish tank thermometer was then submerged into the water. After approximately 30 seconds, the temperature of the mixture leveled out, and was recorded. This was repeated three
Furthermore, you will compare their reactions with water, universal indicator, vinegar and iodine solution to discover what the mystery powder is. Purpose: To identify the mystery powder based on its physical and
Investigating How the Concentration of Hydrochloric Acid Affects the Speed of the Reaction with Marble Chips
Planning Firstly here is a list of equipment I used. Boiling tubes Weighing scales Knife Paper towels 100% solution 0% solution (distilled water) measuring beakers potato chips Cork borer. We planned to start our experiment by doing some preliminary work. We planned to set up our experiment in the following way.
For this experiment, you will add the measured amount of the first sample to the measured amount of the second sample into its respectively labeled test tube then observe if a reaction occurs. In your Data Table, record the samples added to each test tube, describe the reaction observed, if any, and whether or not a chemical reaction took place.
About 1 gm. coarse powder was weighted and transferred to a 500 ml conical flask containing 100 ml of water. It was maintained at moderate boiling for 30 minute on water bath. It was cool and filtered in to a 100 ml volumetric flask. Volume was diluted by adding sufficient amount of water. The decoction was poured in test tube, and then shaken in a lengthwise motion for 15 seconds. They were allowed stand for 15 minutes and the height of foam was measured to determine the foaming index.
Then, repeat steps 7-11 another 4 times but with the room temperature water. For the room temperature water just leave it in the room but try not to change the room’s temperature. 15. Try to put all your recorded data into a table for organization 16. Repeat the entire experiment for more reliable data.
The volume of the liquid inside each beaker after each day was a starting from 200 mL to 170 mL, 170 mL to 160 mL, and 160 mL to 137 mL. This answers my problem question because it shows my data going up to my final answer of 96 grams and a volume of 137 mL this means it has started off a number and has increased and then decreased to a lower number than that start number then increased to a higher number than that other increase. The independent variable is the solutions, the dependent variable is the mass, the controlled variable is temperature, egg classification, and the time. My hypothesis was proven in a way but not thoroughly made clear through each day which means I kind of got it correct I had it correct when the egg will shed or melt its shell that's really
Also, the temperature of the bath water should be recorded. For the next 15 minutes, the location of the dye should be recorded. Also, the temperature of the bath water should be recorded every other minute. All the data should be recorded in table one and used for analysis.
One of the best methods for determining mass in chemistry is gravimetric analysis (Lab Handout). It is essentially using the the mass of the product to figure out the original mass that we are looking for. Thus the purpose of our experiment was to compare the final mass in our reaction to the initial mass and determine the change in mass.
In a 100ml beaker 30mls of water was placed the temperature of the water was recorded. 1 teaspoon of Ammonium Nitrate was added to the water and stirred until dissolved. The temperature was then recorded again. This was to see the difference between the initial temperature and the final temperature.
Next I will measure out different concentrations of acid, these concentrations are, 30ml acid no water, 25ml acid 5ml water, 20ml acid 10ml water and 15ml acid 15ml water. I will then put the powdered marbled chips in the chronicle flask along with the acid and put the stopper on top. I will then record how long it takes for it to fill the measuring cylinder up. I will repeat each experiment 4 times so I can work out an average
We then put the stopwatch on and left them for half an hour. After we weighed each potato tube and recorded our results. We did the experiment twice. We did this to make sure our results were correct. Preliminary method: We did everything the same as in our other experiment except we
An investigation into how changing one variable influences the rate of reaction between marble chips and dilute Hydrochloric acid
We decided to use 2 minutes, as this gave the best results. We repeated the experiment fifteen times, firstly heating 50cm3 three. times, then add 25cm3 of water each time, so from 50cm3 to 350cm3. After each repetition we rinsed the beaker so as to make this a fair. experiment.
