To separate sugar from its mixture with sand, a proportionally large amount of water is added to the mixture and shaken vigorously to allow the sugar to dissolve. The solid-liquid mixture is filtered using a porous material to retain the sand on the filter and to allow the liquid portion to pass through. The liquid contains the sugar originally present in the solid mixture.Know More
In a laboratory setting, prepare a mixture of known amounts of sand and sugar in a test tube or flask. Add water to the mixture's container, then shake the container to allow the sugar to dissolve properly in the water. Meanwhile, set up a filtration system consisting of a funnel, a fan-folded filter paper and a filtrate flask. Dispense the solid-liquid mixture from the container to the filtration setup. Through this process, sand is retained on the filter paper, while the sugar solution passes through the paper as the filtrate. If both materials need to be recovered in pure form, the sand and the sugar solution may be dried up by evaporating the water.
The physical separation of sand and sugar is made possible by their differences in solubility. Sand is insoluble in water, while sugar is readily dissolved as soon as it comes in contact with water.Learn more about Solutions & Mixtures
Yes, putting sand and water together in a container is classified as a mixture. This is because the physical properties of sand and water remain unchanged when added together.Full Answer >
Sand is a mixture, not a compound. Sand is classified as a heterogeneous mixture because it does not have the same properties, composition and appearance throughout the mixture. A homogeneous mixture has a uniform mix throughout.Full Answer >
Sugar dissolves in water because both substances are polar substances. Water dissolves the majority of substances that are polar or ionic. The fact that sugar dissolves in water is unusual because most molecular compounds are nonpolar and are not water-soluble.Full Answer >
According to the Purdue University College of Science, sugar dissolves easily in water due to the fact that sucrose molecules are held together with weak intermolecular forces. The energy produced when these molecules bond with water is more than enough to offset the energy needed to break those bonds in the first place.Full Answer >
