Separate Materials Lab

We had to first gather 3 eggs and 3 cups. Put one egg in each cup then we had to get the 3 solutions that were being used for the experiment, which was mouthwash, syrup, and salt water. We labeled the cups for which solution went which what egg and then we had to measure each egg before putting it in the substance for 24 hours. To measure we got a string and wrapped it around each egg to get its circumference then we took that measurement(the circumference of the string) and converted the string to a ruler to find out the circumference.

Weigh the large block on an electronic balance and write the mass on the data table. Record the masses of the metal blocks in grams and maintain the certainty of either the milligram or analytical balance. When you are finished recording show your data to your instructor for their initials.

Hypothesis: If we use these materials and use magnets, water, burners, and filters on the mixtures and elements given we should determine what kind of effect these materials given will have on these mixtures and elements, physical or chemical.

To understand the different separation methods and techniques that depend on the chemical properties of a specific substance. Also to become more comfortable with performing those actions of separation so I have them in the future. For this experiment, I will separate a mixture of four distinct substances: sodium chloride, benzoic acid, silicon dioxide, and iron fillings into pure beings.

Add a magnet to the bottom of the paper and observe what happens. In experiment 2 fill a small beaker until it is half-empty with cold water. Obtain the test tube in the warm water and pour it into the cold water. In experiment 3 place a piece of magnesium in a test tube and add 10 drops of hydrochloric acid. Feel the bottom of the tube. In experiment 4 scoop a small amount of sodium bicarbonate to a test tube. Add 10 drops of 6M HCI. Feel the bottom of the tube. In experiment 5 combine 5 drops of barium chloride and 5 drops of sodium sulfate. In experiment 6 mix some sodium chloride in a test tube with 2 mL of

5. Substances in a mixture can be separated depending on the substances involved. You can use a magnet to separate a magnetic substance form a non-magnetic one, filtering, and evaporation. For example, when I put the

The composition of a pure substance is constant, and thus pure substances have characteristic physical properties that do not change and this is why we are able to separate each element in this lab experiment. Examples of physical properties that can be used to describe pure substances include solubility, conductivity, magnetism, density, boiling point, and melting point.

From the experiments, the following have been found to signify a chemical reaction, color change, odor change, energy change, formation of a gas, and formation of a solid. In Experiment 3, observations noted a color change to bright yellow. Chemical reactions result in the formation of new substances with new properties, Experiment 3 had two compounds combined to produce two new compounds. Experiment 4 also had a color change, after the copper was held in the flame it turned a silvery blue. A solid compound formed after the combination of oxygen and copper, proving it to be a chemical reaction.

Understanding boiling point, density, mass, and volume and being able to classify them as either intensive or extensive properties will enhance our knowledge of these properties and ultimately innovate our daily lives. For instance, unknown material can be identified by knowing the boiling point, density, mass, and volume of the substance. Intensive properties aid the process of identifying unknown substances for the reason that they don’t depend on the quantity of the substance nor do they alter. Although, extensive properties do alter due to quantity that is present, they differentiate between matters. Therefore, both of the experiments will aid in the knowledge and

With the magnet they were separated quite easily. When almost boiling the sand, salt and benzoic acid, it didn’t seem like I was doing the right things. I could see the remnants of the benzoic acid floating inside the beaker. It seemed like they were separated just fine, but not necessarily dissolved. When doing the filtration part, the paper also was hard, because the crystals from the ben, acid were already forming making it quite difficult to get everything out of the cup. It took me some time for the salt to

During this experiment students will take a mixture and separate it into its’ pure substances. A mixture is a combination of two or more substance. These substances cannot be combined chemically but more physically. The pure substances are substances that cannot be separated any more by physical means. The students will learn the difference of these two meanings during the experiment.

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.

The experiment itself really connects to ideal principles of buoyancy and how salt can affect objects being more buoyant in water. One thing that shares this same exact principle is the idea of boats and how they are able to float on water. Boats are able to float because of what we like to call buoyancy. It is a thing that has to do with density of the water that the boat is maneuvering on. It relates to this experiment because the cup was able to float on the water because the water is denser.

The hypothesis stated that, firstly, the materials could be sifted through the sieve. Secondly, the iron filings could be separated from the mixture. Thirdly, that the salt would be removed from the mixture, through dissolving and evaporation. Fourthly, the polystyrene beads could be removed in the dissolved mixture. Finally, the salt mixture could be separated, using evaporation. The reason why iron filings come first is because magnetism is a quick and easy method to separate the iron filings, meaning that it could be separated straight away, so it’s out of the way. The salt is dissolved next because the rest of the mixture in insoluble, meaning it is unable to be dissolved in water. Dissolving salt, here, means that the other

On September 29, 2017, in class a lab was done on Mixed Substances and Investigating Mixtures. The objective of the Mixed Substances lab is to see how properties of individual substances compare with properties of mixed substances. The definition of a mixture is a combination of two or more substances that are physically mixed but can be separated. There are two different types of mixtures, heterogeneous and homogeneous. A heterogenous mixture is a mixture consisting of dissimilar parts or elements. A homogenous mixture is a mixture that is uniform in structure or composition throughout the substance. The prediction statement or hypothesis is, If the water and cornstarch are in the same bowl and they combine then a thick liquid will form. The objective of the Investigating Mixtures lab was to observe that not all liquids behave the same way when mixed with other liquids. The hypothesis is, If water and oil are put in the same container and they are mixed, then they will separate from each other.
