Baking Soda Vs Epsom Salt

The hypothesis is correct. Potassium chloride mixed with silver nitrate creates a white precipitate. Barium

Make sure the Classroom temperature is the same each time I do the investigation. This is because; a higher classroom temperature can increase the rate of reaction resulting in results that do not form a pattern.

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.

Lastly, the water that the beakers were washed with may have steadily lowered the temperature of the glass throughout the trials and therefore affected the base temperature of the vinegar and the temperature of the

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 compound was tested for the presence of ammonium, carbonate, sulfate, chloride, and nitrate, as seen in Table 2. The nitrate test produced a precipitate, indicating the presence of the nitrate ion in the compound. At this point it was hypothesized that our unknown compound was calcium nitrate.

The flame test had a variety of results. Most of the known compounds did not match our unknown except for Ca(NO3)2. Both Ca(NO3)2 and the unknown compound had a deep red/orange color flame. While Ca(NO3)2 had the closest results two other compounds had slightly different results but not different enough to rule them out. Those other two compounds were CaCl2 with a yellow/ orange color and CaCO3 with a reddish color.

Unknown Mixture was SrCI2 and CuCI2 because looking at the different flames of all the salt solutions the two flames that had the same colors as the unknown mixture did. The color of a vibrant red was from the SrCI2 and the Green blue colors came from the CuCI2. Since the

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.

In 2-4 paragraphs, explore the “who”, “what”, “why”, “how”, “when” of the theory or concept you are investigating.

The purpose of this experiment is to identify an unknown substance by measuring the density and boiling point. I will be able to conclude which substance is my own from a list of known options stating what its real boiling point and density is.

When it comes to art there are a million things you can use to create a masterpiece, well how about salt? When salt reacts to water and paint it creates starburst, some of them can be large or small it depends on the salt. That’s where my experiment comes to place, my team and I tested Iodized, Epsom, Sea, Rock, Canning, and Table salts. We used table salt as a control, when we conducted the experiment we used 140lb paper, tube paints, our various salts, and our paint brushes. After recording the results, Epsom salt had the most successful individual starburst. Epsom salt is the best option in this experiment because it has medium sized salt crystals, it makes the best starburst, and it produces crystals in the paint which makes it look like
