Separation Of Mixtures Lab Report

Because salt dissolves in water, we added water to the salt and sand mixture. Sand is insoluble in water making the sand not dissolve. The mixture containing of sand and salt water was then filtered with filter paper. The filter paper allowed the salt water to pass through because it is a liquid while not allowing sand to pass through because it is a solid. The salt water was then collected in a pre-weighed 250-mL (67.88 gram) beaker while the sand and filter paper was put in a pre-weighed (52.02 gram) 100-mL beaker. The water was then evaporated because we left both beakers to dry overnight.

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.

    D.a poorly sorted mix of gravel and sand.   Answer Key: C   Feedback: The correct answer is C. a moderately sorted mix of sand and silt.     Question 2 of 33 3.03/ 3.0303 Points Bag B contains Correct  A.well-sorted sand.     B.clay.     C.a poorly sorted mix of sand and silt    D.a poorly sorted mix of gravel and sand.

Water flows through a filter designed to remove particles in the water. The filters are made of layer of sand gravel, and in some cases, crushed anthracite. Filtration collects the suspended impurities in water and enhances the effectiveness of disinfection the filter are routinely cleaned by backwashing.

The anoxic layer is very deep above the areas with coarse sand. This is in accordance with what was mentioned in the introduction. The coarse grained sand has more water passing though it to increase the

no chemical bonding takes place in mixtures • Most mixtures can be separated by physical means Physical separation 1. A mixture of iron filings & sulfur can be separated by using a magnet to attract the iron (magnetism) 2. Distillation using heat 3. Filtration exclusion 4. Crystallization using attraction 5.

| Can see particles of both. When mixed with water salt dissolves and sand is left.After filter sand is left and salt-water goes through.After evaporations of salt-water, salt is only left in dish.

this experiment had a similar scenario to part A except the metals were switched and replaced with

There are various techniques to separate a mixture of compounds from each other. One of the commonly used way to isolate compounds from a mixture of two compounds is called extraction. This method of extracting two compounds from each other relies on the different solubility of the compounds in two different solvents.

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:

Because of the small size, the particles float on the surface of water and often travel long distances during rainstorms. When there are too many of these sediments, the water

three substances formed in like manner by the violence of fire comes into one mixture,

The filters consist of finely crushed coal, about one meter in depth, and sand, half a meter in depth. This provides the final step in the treatment process.

1. Obtain a sample of the mixture. The mixture you will separate contains three components: NaCl, NH4Cl, and SiO2. Their separation will be accomplished by heating the mixture to sub-lime the NH4Cl, extracting the NaCl with water, and drying the remaining SiO2.

Instead, the polystyrene beads were removed by hand, considering that there were no spatulas. Using a spatula would have resulted in a more scientific method, allowing to make use of all lab equipment. In addition, when pouring the salt solution into the funnel, this could have been taken into consideration by slowly, and carefully, pouring the salt solution into the funnel, so that it didn’t overflow. However, the salt solution was still able to successfully filter through. Finally, time could have been managed more efficiently so that the water in the salt solution dissolved faster, using a Bunsen burner, meaning that the entire experiment would be completed in one day. However, less water could have been poured into the evaporating dish, resulting in less time for the water to dissolve. But, using the Bunsen burner would have been a scientific method to complete this
