Separating the Mixture of River Sand, Table Salt, and Iron Shavings

To separate the mixture of river sand, table salt, and iron shavings in the chemical flask, you can follow the following sequence of steps:

1. Use a Magnet to Remove Iron Shavings: - The first step is to use a magnet to separate the iron shavings from the mixture. Iron is a magnetic material, so it can be easily separated using a magnet. - *Source: "Iron is a magnetic material, so it can be separated from a mixture using a magnet."*

2. Dissolve the Salt in Water: - After removing the iron shavings, the next step is to dissolve the table salt in water. Table salt (sodium chloride) is soluble in water, so it will dissolve, leaving the sand behind. - *Source: "Table salt (sodium chloride) is soluble in water and can be separated from a mixture by dissolving it in water."*

3. Filtration to Separate Sand and Salt Solution: - Once the salt is dissolved, the mixture can be filtered. The sand will remain in the filter, while the salt solution will pass through. - *Source: "Filtration can be used to separate sand from a salt solution. The sand will remain in the filter, while the salt solution will pass through."*

4. Evaporate the Water to Obtain Pure Salt: - The final step is to evaporate the water from the salt solution, leaving behind pure salt. - *Source: "Evaporating the water from a salt solution leaves behind pure salt."*

By following these steps, you can effectively separate the mixture of river sand, table salt, and iron shavings in the chemical flask.
