Brooke Thomas September 13, 2012 Separating Salt and Sand Lab Report Separating components of a mixture of salt and sand and calculate the mass of each. Salt is soluble and sand will sink to the bottom, you can separate the rest with filtering and distillation (boiling). If salt and sand are a mixture, then we can separate them by physical processes. Materials Ring with ring stand Funnel Wire triangle Stirring rod Filtering paper Beakers (mall and mall) Rinse bottle Evaporation dish Digital balance
Calculator Hot plate (stove top) Salt/sand mixture Procedure Weigh your dish(in grams) and filter by there selves and write it down. Put your wire triangle on your ring attached to the ring stand . Place the funnel down inside of the wire triangle. Fold your filter paper (as shown in figure 4. 8) and put inside of the funnel. Mix together your salt and sand mixture with ml of water in the mall beaker. Stir with stirring rod. Place mall beaker under the funnel (as shown in figure 8. . Pour mixture into funnel with the filter paper. Catch water inside of the mall beaker . Take filter paper out to dry with the sand still on it. Pour the salt water mixture into the evaporation dish. Place dish on hot stove top. Let water boil off. Weigh evaporation dish(in grams) with the salt after the water evaporates off and write amount down. Subtract the evaporation dish from the evaporation dish with sand and you have the mass of the salt.
Weigh the dried filter paper with and(in grams) and write down. Subtract the filter papers original total from the one with sand to get the mass of the sand. Compare your final masses to the original amounts.
