A beaker contains a mixture of sand and salt. A student add water to deserve this all. Which process can be used to separate the sand and salt?
The process that can be used to separate the sand and salt is called filtration. This involves pouring the mixture through a filter or a sieve, which allows the water and salt to pass through while retaining the sand. After filtration, the water and salt can be collected and the water can be evaporated to obtain the salt.
The process that can be used to separate the sand and salt from the mixture is called "filtration." Here are the step-by-step instructions:
Step 1: Set up a filtration apparatus. You will need a filter paper, a funnel, and a container to collect the filtrate (liquid).
Step 2: Place the funnel in the opening of the container and fold the filter paper in the shape of a cone or cylinder. Put the filter paper in the funnel.
Step 3: Pour the mixture of sand, salt, and water into the funnel while keeping the container underneath to collect the filtrate.
Step 4: The sand particles being larger in size will be trapped by the filter paper, and the water with dissolved salt passes through as filtrate. Let the filtration process continue until all the liquid passes through, leaving only the sand on the filter paper.
Step 5: Carefully remove the filter paper with the trapped sand and place it in a separate container. Leave it to dry, and then you'll have the separated sand.
Step 6: To obtain the salt, you can use evaporation. Pour the collected filtrate (saltwater) into a shallow dish and leave it in a well-ventilated area or apply gentle heat to speed up the process. As the water evaporates, the salt will crystallize and can be collected.
By following these steps, you should be able to separate the sand and salt from the mixture through filtration and evaporation.
To separate the mixture of sand and salt, you can use the process of filtration. Here's how you can do it:
1. Set up a filtration apparatus: Place a filter paper or a funnel with a filter paper in a clean funnel holder. Position it over an empty beaker or container to collect the filtrate.
2. Carefully pour the mixture of sand and salt into the filter paper. The sand particles will be retained by the filter paper while the salt and water will pass through.
3. The collected liquid in the beaker is called the filtrate, which contains the dissolved salt and water.
4. Now, to separate the salt from the water, you can use the process of evaporation. Pour the filtrate into an evaporating dish or a heat-resistant container.
5. Heat the evaporating dish gently using a Bunsen burner or a hot plate. As the water evaporates, the salt will start to crystallize and form solid deposits.
6. Once all the water has evaporated, you will be left with the salt crystals in the evaporating dish.
So, the two processes involved in separating the mixture of sand and salt are filtration and evaporation. Filtration separates the sand from the salt-water mixture, while evaporation separates the salt from the water.
