Identify The Relationship Between Mixtures And Physical Differences

523 Words3 Pages

The first hypothesis that I wrote, which states that I would be able to separate the components of a mixture and identify the relationship between mixtures and physical changes if I used the components’ differences in characteristic properties and the three processes of sublimation, filtration, and evaporation, is true. Firstly, I was able to separate the components of a mixture into its three components: sand (SiO2), Ammonium Chloride (NH4Cl), and salt (NaCl). I was able to accomplish this by taking advantage of the characteristic differences of the three substances (sand does not dissolve in water while salt does and ammonium chloride is the only substance in the mixture that goes through sublimation when heated), and applying that knowledge to the usage of sublimation, filtration, and evaporation as tools to separate out the substances from the mixture. …show more content…

Since I was able to separate out the sand (SiO2), Ammonium Chloride (NH4Cl), and salt (NaCl) from a mixture using physical changes, it stands to reason that a mixture is composed of substances that have been physically combined; therefore, the mixture is able to be separated using physical changes. Furthermore, my second hypothesis, which states that I would be able to calculate the percentage of each substance and the approximate mass of each substance in the mixture if I measured the mass of the mixture before and after it goes through sublimation, filtration, and evaporation and subtracted the after values from the before values, is partially true. For one thing, I was able to find the masses of sand (SiO2), Ammonium Chloride (NH4Cl), and salt (NaCl) to be 6.158 grams, 1.222 grams, and 2.620 grams respectively. This is because I subtracted the measured before and after values for each substance as it was eliminated from the mixture through sublimation, filtration, and

In ranking the smallest difference between original mass and recovered mass was the oil(17.941g), sand(3.990g), CuSO4(6.556g), and the KNO3(2.751g). Factors that contributed to error had been not fully transferring the mixtures from the flask to another container. Another source could have been human error from spillage of some of the components out of the flasks. These variables affected the accuracy and precision of the experiment. The purest sample of KNO3 crystals was not obtained because of these errors.

The first experiment tested if the it responded to the environment. To test this factor, the vial substances were tested to watch and observe how they respond in hot and cold water. Vial B responded to the environment when we added the hot water and the cold water. It was cohesive and in both tests it was observed how drastic the changes were from the beginning of the experiment to the end. Where in Vial A, it stayed separate for both tests.

Beneath Our feet Experiment 1: We put different types of rocks in to three piles that were called Igneous, Metamorphic and Sedimentary. Igneous comes from a volcano. Metamorphic is heat and pressure and Sedimentary is a mixture of conglomerate, fossils and layers. Experiment 2: We put chalk and 3 spoons of sand into a cup and shook it really hard. Some of the sand turned pink which was the colour of the chalk.

Sludge Lab Report

The objective of the sludge lab was to determine how many different pure substances were in the sludge by using the methods and techniques we have learned throughout the year. We had to pick separation methods so we could separate our sludge and then test characteristic properties on our separated liquids and solids. This experiment made us use our knowledge on characteristic properties to pick the ones we should test to help us identify our pure substances. Characteristic properties are properties that help identify a solid or liquid. Each solid or liquid has a certain density, boiling point, solubility, flammability, so if you know what each one is then you can use that information to help you identify your solid or liquid.

Observations: As the ice (solid H O) was being heated up, the ice went through a process of melting/fusion and then eventually, the melted ice changed into boiling water (liquid H O). In other words, examining water (a system) undergo a physical change. The temperature (example of a physical property) is a great indicator for describing this specific sample/experiment.

IR spectra were collected for the given sample, SMH, as well as many provided sweet substance that could have been the composition of the unknown sample. Each spectrum was collected from 700 cm-1 to 1600 cm-1. The unknown sample IR is shown in Figure A. The goal of this experiment was to determine the composition of this unknown sample.

Air, baking soda, and ink are examples of homogeneous mixtures. Bronze is also a homogeneous mixture because it is a solid mixture, known as an alloy. Heterogeneous mixtures does not dissolve easily or spread evenly, making it easy to identify the different properties from each region and to separate. Colloid and suspension substances fall under this category. With granite, dirt, and fruit loops, their initial substance could be identified and physically separated without changing it

Also, salt is an ionic compound and not a polar covalent compound, even though it did not melt last, due to the fact that the elements Na and Cl, both lose or gain an electron and then bond because of their opposite charges, which is a property only ionic bonds possess. The wax was the only substance whose results were synonymous with my hypothesis, since it required a low temperature for its melting point and was not soluble in water, both properties of nonpolar covalent compounds. Potential sources of error included not labeling the spots each substance was placed in the aluminum foil boat, seeing as the result for sugar seemed to be the correct conclusion for salt and vice versa. A future experiment would involve individually testing each substance in an aluminum foil boat, of the same brand, on a heat plate in order to avoid uncertainty. Each substance should be timed to record the precise time each substance began to melt or burn.

Explain How The Surface Area Of The Solute Affect The Rate Of Dissolution

699 Words | 3 Pages

The guiding question, why do the surface area of the solute, the temperature of the solvent mixed affect the rate of dissolution. To answer this question we used three hypotheses to test; if you increase the surface area than the rate of dissolution increases, If you increase the temperature of solvent then the rate of diffusion increases, If you increase the amount of agitation then the rate of dissolution. We predicted that changing the stress, surface area, temperature, and stirring in a controlled experiment it would forward the rate of dissolution. Based on the background on making lemonade, when sugar is added to water and stirred the sugar (solute) dissolves quickly, when sugar (solute) is fine, the temperature is raised, and agitation is increased the solution dissolves at an increased rate.
