The mixture of sodium bicarbonate and sodium carbonate can be separated due to the different temperatures at which the carbonate and bicarbonate decompose. This separation is the focus of the experiment. The bicarbonate decomposes when heated by the Bunsen burner. The carbonate also will decompose but at a much higher temperature. So, when the bicarbonate is heated it decomposes into carbonate, and during the decomposition it releases water and carbon dioxide. Furthermore, the amount of water and carbon dioxide released can be found by finding the difference in mass of the original mixture (before heating) and the final mixture (after heating). The mass of the water and carbon dioxide can be used to find the percent composition of bicarbonate in the mixture.

Since we obtain an unknown proportion of a mixture, it’s important to mention that a mixture is a result of a combination of two or more pure substances that do not react chemically. The physical properties of a mixture depend on its composition because the amounts of each substance making up a mixture can vary. By taking advantage of the unique physical properties of individual components within a mixture, it should be possible to separate a mixture into its components. Mixtures have the following fundamental properties:

12. Place the magnet on the scale to measure the mass of the object. Record the mass in Data Table 5.

The objective of this extraction experiment was to achieve a comprehensive understanding, as well as master the practice, of the technique of separating various individual components of a compound.

First students obtained 8 graduated cylinders and labeled them. Each one contained a different ratio of vinegar and water. These graduated cylinders with the liquid were weighed and recorded.Then, students obtained an Alka-Seltzer tablet and recorded its mass. Then one alka-seltzer tablet was dropped into each of the graduated cylinders. Students had to

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.

3. Test the effect of a magnet on each substance by passing the magnet under

by other substances as well as pure and good. Which are also words that we use when describing

The purpose of this experiment is to familiarize oneself with the general procedures determining a partition coefficient at the microscale level and learn in weighing milligram quantities of materials on an electronic balance, the use of automatic pipets, the use of transfer pipet, and the use of a vortex mixer. Also, to familiarize oneself with extraction

First, record the mass of two 150 mL beakers. Proceed to obtain a sample of unknown 3 and place about 2.5 to 3.0 g of the unknown into beaker 1 and record the mass. Slowly add 50 mL of distilled water into the beaker while stirring the mixture with a stirring rod. Prepare for gravity filtration by placing a funnel in an iron ring attached on a ring stand. Next, begin to fold a piece of filter paper, tearing off the corner of the smaller segment of the paper, and placing it in the funnel.

The purpose of this experiment was to separate a two component mixture using fractional distillation. Distillation is a process of vaporization than condensation of a substance, used primarily to separate substances from a mixture when there are different boiling points. Fractional distillation is when the mixture has multiple substances with similar boiling points, and a fractional column is used to create multiple vaporization/condensation cycles. Fractional distillation is important when two or more substances need to be separated, but they have similar boiling points.

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.

4. Prepare a vacuum filtration apparatus using a buchner funnel. Obtain one filter paper for each one of your samples, weigh them and record their mass in your notebook (label them with a pencil to be able to differentiate them later).

becomes a liquid and some may even evaporate but we know as it is in us to know that it is the same piece of
