Extracting Table Salt and Sand from the Mixture

To separate table salt and sand from the mixture, you can use the process of filtration followed by evaporation. Here's how you can do it:

1. Filtration: - The mixture of table salt, sand, and water can be poured through a filter paper. The sand will remain on the filter paper, while the saltwater will pass through.

2. Evaporation: - The saltwater collected from the filtration process can be heated to evaporate the water, leaving behind the table salt.

Properties of the Substances in the Mixture

When dealing with the mixture of table salt, sand, and water, the following properties of the substances are considered:

1. Solubility: - Table salt (sodium chloride) is soluble in water, forming a saltwater solution. - Sand is insoluble in water and will not dissolve in the water.

2. Boiling Point: - Water has a lower boiling point compared to the melting point of table salt. This property allows for the separation of salt from the saltwater through evaporation.

3. Particle Size: - Sand has larger particles compared to table salt, which allows it to be effectively separated through filtration.

4. Density: - Table salt is denser than water, causing it to settle at the bottom of the container when dissolved in water. This property aids in the collection of the salt after evaporation.

By considering these properties, it becomes possible to separate the components of the mixture effectively.

I hope this helps! If you have further questions or need additional assistance, feel free to ask.
