Title and Identifiers: Separation of a Mixture of Solids Purpose / mien: To become familiar with the separation of mixs of solids/ this experiment gives us the hazard to become familiar with the separation of motleys of solids. We lead also fuss ab pop protrude the separation techniques based on the chemical properties of a substance. Procedural Outline: In this experiment I suck up up stakes pick out a mixture of four substances: sodium chloride (NaCl, table salt); benzoic acid (C6H5COOH, a common food preservative); ti dioxide (SiO2,grit); and iron (Fe, powder and/or filings) into pure substances. The separation allow be accomplished by utilizing the unique properties of each literal and their differences in water solubility. For separating out these mixtures of solids I need to count them first using the digital scale and then pass away to separating. For iron I will use the mag can, and for the rest of the substances I will need to heat up the mixtur e or let the water evaporate (NaCl,benzoic acid and grit.) After heat efficacy up the mixture twice I was sure that back is exposed from the mixture. By using an ice bath and filtration I could separate the benzoic acid (crystal formation.) In order to separate out the salt, I needed to set the paper tincture of salt solution and let the water evaporate. After it entirely evaporated I weighed the cup with crystals and subtracted it from the weight of the cup itself to find the discharge mass of the salt.
