You can't use the same mixture because,a mixture of sand and water is a heterogeneous mixture.In this mixture the particles are not uniform which means they can't desolve into one an other,but the mixture of salt and water is a homogeneous solution because the particles can be desolve into one another to form a solution.
What else can I help you with?
Does salt dissolves when you mix with sand?
If water is present salt is dissolved.
Why is 'Sand is mixed with salt' a physical change?
'Sand is mixed with salt' is a physical change because it involves a combination of two substances without altering their chemical identities. The individual particles of sand and salt retain their properties and can be separated by physical means, such as dissolving the salt in water or using filtration. No new substances are formed during this process, which is a key characteristic of physical changes.
What Discribe the following type of mixture and give on example one?
A mixture is when two or more different substances are mixed together but not combined chemically.granite stonedry cereal with nuts and dried marshmallow shapescereal in milkmilkgasolineetc.
Heterogeneous matter composed of two or more pure substances each of which retains its identity and specific properties?
This is the definition of a mixture. Mixtures are combinations of two or more substances that are physically combined but not chemically bonded, allowing each substance to maintain its original properties. This can include mixtures like saltwater or air.
What mixture can be separated through filtration because one of the substances is insoluble in water?
A mixture of sand and salt can be separated through filtration because sand is insoluble in water while salt is soluble. When water is added to the mixture, the salt dissolves, creating a saltwater solution, while the sand remains as a solid. By pouring the mixture through a filter, the sand is trapped in the filter paper, and the saltwater passes through, allowing for the separation of the two substances.
How can the crystalline substances be removed?
This sounds like a physical separation question where the student receives a beaker of sand and salt or sand and sugar and is asked to separate the two substances. The technique is to filter the mixture with water. The sand stays in the funnel, but the salt or sugar crystals dissolve in the water and are pulled through to the flask below. If you need to separate the salt or sugar from the water used for filtration, use a hotplate and evaporation dish to boil away the water.
Does salt dissolves when you mix with sand?
If water is present salt is dissolved.
How do you separate a mixture of common salt and wax and sand to obtain a pure sample of each substance?
To separate common salt and sand, use water to dissolve the salt and then filter out the sand. To separate the wax, melt the mixture and then let it cool to solidify the wax, which can then be physically separated from the other components.

What are two ways to separate nails from sand?
The two ways you can separate nails from sand is by digging it up and raking it :)
Can you separate salt and water with a sieve?
It is virtually impossible to separate salt and water with a sieve unless the two materials have not been touched. This is because when salt is combined with water, it dissolves, and then it is mixed in with the water. To separate these two materials, you have to let the water evaporate, so then the salt is left.
How does a pure substance differ From a mixture?
A heterogeneous mixture contains multiple chemical substances combined in a non-uniform way, whereas a pure substance contains molecules with only one chemical identity. For example, salt is a pure substance, whereas a mixture of salt an rocks is a heterogeneous mixture.
Can you separate gravel and sand with a coffee filter?
As salt is soluble in water, mixing salt and sand in water would result in solid sand, and salt water. When poured through a coffee filter, the sand would remain in the filter, while the salt water would flow through. After letting the water evaporate, salt would remain. You will be left with the two separated solids.
What are elements a mixture of?
Elements are not mixtures. An element is composed of only one kind of atom. A compound is composed of two or more different elements. A mixture is just two or more substances mixed together. A classical experiment in school is to take a mixture of two substances, sand and salt; then to decide how to separate the two substances. That is usually done by putting them both into water; the salt dissolves thus allowing the salt to be recovered by boiling the water away. The sand (and any remaining water) are then placed on a filter paper. This lets the water through but not the sand, which might need a little more drying.
