Pl i'll give brilliant, experiment: mixtures here are your goals for this lesson: utilize a filter to separate a mixture of sand and water summarize your findings many tasks in chemistry involve separating mixtures. for example, crude oil by itself has very few uses, but many important substances are separated from crude oil. in this investigation we will attempt to separate sand from salt water, and salt from water. if you do not have access to sand, you can use small pebbles or bbs. these supplies are needed: salt, water, sand, a measuring cup, a balance, filter paper 1. measure 5 grams of salt and 10 grams of sand using the balance. 2. mix together the salt and sand. 3. add the salt and sand mixture to one half-cup of water. 4. stir the mixture. 5. filter the mixture. 6. dry the sand on the filter paper. summarize your findings in a scientific report. include your hypothesis, observations, data, and conclusions. be sure to answer the questions below in your summary as well as including your findings. where is the salt after you filter? where is the sand? how could you separate the salt and water? what other mixtures could be separated in this way? what did you find out from this investigation? be thoughtful in your answer.

Answer quicky! create a mixture of salt and sand. how can you separate the sand from the salt? pour some salt and sand into a cup and stir. add water to the mixture and stir. the salt dissolves in water; the sand does not. use a funnel with a paper filter. pour the mixture through the filter into another cup. the salt goes through; the sand is left behind. let the water evaporate for a couple hours. the salt is left behind. create a mixture of nails, toothpicks, and plastic mixers. how can you separate these three objects? would you use shape to separate this mixture? place all three components in a bowl. use a magnet to separate the nails. plastic and wood do not stick to magnets. use water to separate the toothpicks, since they float. you can pick them with your hands. the plastic mixers are left behind. (1)what physical properties did you use to you separate each mixture? (2)could you have used other properties? (3) are these mixtures homogeneous or heterogeneous? why? (4)what are different types of mixtures, and how do they differ?
