Sand and salt can be separated using filtration because they have different physical properties. When mixed with water, salt dissolves, forming a saline solution, while sand remains undissolved. By pouring the mixture through a filter, the sand is trapped in the filter paper, while the saltwater solution passes through. This process allows for the effective separation of the two substances.

What was the result of the mixture of salt sand and pepper?
When salt, sand, and pepper are mixed together, they can be separated by using techniques such as filtration, where the salt and pepper can be dissolved in water and separated from the sand. This separation is possible because salt and pepper are soluble in water, while sand is not.
What is a mixture where the particles can be easily seen and separated?
A heterogeneous mixture is one where the components are visibly different and can be easily separated using physical methods like filtration or sorting. Examples include a mixture of sand and salt, where the sand particles can be seen and separated from the smaller salt particles.
Why do you add water to the salt and sand mixture?
Assuming that you're trying to separate the sand and the salt: adding water will dissolve the salt but it will keep the sand. So the sand can be separated by filtration and then the water can be evaporated leaving behind plain salt.
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.
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 was the result of the mixture of salt sand and pepper?
When salt, sand, and pepper are mixed together, they can be separated by using techniques such as filtration, where the salt and pepper can be dissolved in water and separated from the sand. This separation is possible because salt and pepper are soluble in water, while sand is not.
How can a mixture be separated by using physical properties?
A mixture can be separated by physical properties such as differences in boiling points, solubility, density, or magnetic properties. For example, a mixture of salt and sand can be separated by dissolving the salt in water and then filtering out the sand, as salt is soluble in water and sand is not.
What is a mixture where the particles can be easily seen and separated?
A heterogeneous mixture is one where the components are visibly different and can be easily separated using physical methods like filtration or sorting. Examples include a mixture of sand and salt, where the sand particles can be seen and separated from the smaller salt particles.
What are combinations of substances that cane separated by physical processes?
Substances like sand and gravel can be separated by techniques such as sieving or filtration. A mixture of oil and water can be separated using a separating funnel based on their immiscibility. Salt and water can be separated by evaporation, leaving behind the salt as a solid.
Why do you add water to the salt and sand mixture?
Assuming that you're trying to separate the sand and the salt: adding water will dissolve the salt but it will keep the sand. So the sand can be separated by filtration and then the water can be evaporated leaving behind plain salt.
How To Separate Sand And Water?
Sand and water can be separated by Filtration.
A container contains a mixture of sand salt and pebbles.how can each substance be separated from the other?
To separate sand from salt and pebbles, use a sieve to filter out the larger pebbles first, then add water to dissolve the salt and separate it from the sand through filtration. To separate salt from sand and pebbles, dissolve the salt in water and then evaporate the water to obtain the salt crystals, leaving the sand and pebbles behind. To separate pebbles from sand and salt, use a sieve or filtration to separate the larger pebbles from the sand and salt mixture.

What properties will you use to separate sand and water?
Sand is insoluble and can be separated by filtration.
What separate sand and salt solution?
filtration
Explain why is water separate from sand?
Water can be separated from sand by decantation or simple filtration.
