Mystery Mixture Lab Report

We were assigned mystery powder convertible which contained calcium carbonate, baking soda, and sucrose. We found out that the mystery powder had calcium carbonate because when it reacted with iodine it turned orange/brown. When calcium carbonate reacted with vinegar it had a fizzy-like reaction. It also reacted with hydrochloric acid and that caused it to bubble. When we tested the mystery powder it also turned orange/brown when we added iodine. Also when we added vinegar and it also fizzed like the calcium carbonate. Again when we added the hydrochloric acid it reacted exactly like calcium carbonate, lots of bubbles were made. We know that the calcium carbonate was in the mystery powder because it had similar reactions.

In the last test, we had to test out a mystery powder (powder A, B, C), in its own separate test tube, in order to solve the Sherlock Holmes Mystery. Our group had powder C. When we mixed water in the mystery powder, it did not dissolve. When the litmus paper was put into the test tube it turned blue. When the vinegar was mixed it bubbled/foamed up. When we mixed the iodine solution, there was no reaction and the solution turned to a dark brown/black color. When we mixed in the baking soda there was no reaction and it turned to an even darker color.

In the experiment “White Before Your Eyes” four various white powders were experimented on using various liquids (baking soda, cornstarch, sugar and a mystery powder). The purpose of this experiment was to discover what powder/mixture of powders the substance was.

In order to show you why these students believe the mystery mixture is a combinations of NaHCO3 & C6H8O7 I will need to show you the mixture’s chemical and physical properties. The NaHCO3 & C6H8O7 mixture is a bright white color, and has a slight airy smell. The claim also has a powdery white substance or the NaHCO3. It also has small white spheres, that resemble the mystery mixture’s, which is probably the C6H8O7. The students have also learned through experimentation that if you leave the

The primary goal of this laboratory is to correctly identify an unknown substance. To achieve this task, one may use various tests that reveal both chemical and physical properties of a substance. By comparing the results of a known substance and the unknown substance, one may eliminate alternative possibilities and more accurately predict the undisclosed compound. Furthermore, by performing these tests, data can be collected and verified regarding chemical and physical properties of the unknown. Understanding the chemical properties of a known substance aids one’s understanding of the unknown based on comparative analysis of the results of the tests.

In this lab, a mixture of three solids was separated to their individual components through decantation,

HCl, it is strong acid and when blended with ammonia, it produces a dense insoluble chloride fog.

The goal of the experiment was to identify Unknown 33A and 33B. Unknown 33A was a white, crystalline solid that had a sweet cherry smell and Unknown 33B was a beige, yellowish color liquid that was translucent and had a viscosity similar to water. Also, the liquid was homogenous and smelled sour, similar to mildew.

Counterclaim:I disagree with the other group that thinks it's baking soda,citric acid, epsom salt. I disagree with them cause me and my partner tested both thoughts of each group. The first thing me and my partner did was put it in a well tray and put water in it. Then we tested the temperature the mystery mixture was 15.9, baking soda and citric acid was 16.2 degrees Fahrenheit, and baking soda citric acid and epsom salt was 16.8. After we did this we put 10 drops of water in them and left them overnight. When we came back the next morning we looked and they all turned to a crystal looking thing on the bottom of the well tray they were all white but baking soda, citric acid and epsom salt looked a little different because at the bottom it had more white color. But for baking soda and citric acid it left barely any color just like the mystery mixture. That is why I disagree with baking soda, citric acid and epsom salt.

Aim: To classify unknown substances according to their structure type and to observe how the structure of materials affects their uses.

The general thought of mixing vinegar and baking soda together to create a chemical reaction has been practiced many times over in science classes around the world. At times, the reaction was used to propel a small rudimentary rocket, or as in the case of this experiment to blow up a balloon. The anticipated end result of this experiment was always intriguing to the youngster that watched in wonder. When the baking

The guiding question of this ADI lab was, “What are the identities of the unknown compounds?” The goal of this lab was to understand the relationships between moles and molar mass to find the identity of unknown compounds. The mole can be used to measure small amounts of a substance or is used to convert from unit to unit using dimensional analysis. One mole is equivalent to the molar mass in grams of that substance. If you start with the moles of an unknown substance, multiply it by a given compound’s molar mass, and then divide it by however many moles are in the compound of your choice, you will get the mass of the compound. With that answer you can then compare with mass of the compound in the bag to determine its identity. We first started

The aim of this experiment is to use separation techniques to separate a mixture containing polystyrene beads, salt, sand, gravel and iron filings.

If soap was added to the list of ingredients and was mixed into the mixture of water and oil, I think the soap would mix with the water but the oil will remain at the top and unmixed. The mixture was a heterogenous because even though they were in the same constiner, you were able to spot the individual substances by themselves. Going back to reanalyze my hypothesis, I have come to the conclusion that my hypothesis is correct because I said the water and oil would not mix

Here is one of them, baking soda, citric acid, and Ascorbic acid. Some of the people disagree with this claim and here is why. When setting overnight the mixture turns color, it has a tint of yellow while the mystery mixture stays clear. When the class did a large-scale experiment on the mystery mixture and baking soda, citric acid, and ascorbic acid, they found that it did not fizz and bubble as long as the mystery mixture, when added to water. It was actually 113 seconds while the mystery mixture was 125 seconds. They also found out that the temperature was 16.6℃ and the mystery mixture was 16.7℃. So their claims temperature was point one off. The physical features in this mixture were also off. The citric acid and ascorbic acid made it so that there was a lot more crystaly objects in the mixture than in found in the mystery mixture. The ascorbic acid crystals were way too small to be the mystery
