you have been asekd to analyse some salt-contaminated soil. How would you separte the salt from the soil? (a) write out the method that you would use to obtain pure dry salt and pure dry soil. (b) draw a labelled diagram showing how you equipment would be set up for each stage of your separtion. obviously this is not an answer it is a question i just want question a because i really need this science mark anyone? please? please help me :P
To obtain pure dry salt, you can dissolve the saltwater solution and then evaporate the water to leave behind the salt crystals. To obtain pure dry soil, you can collect soil samples, dry them out in an oven or under the sun to remove moisture, and then sift the soil to remove any impurities such as rocks or debris.

What are the method of collecting undisturbed soil sample?
One method is using a soil auger to collect a cylindrical sample by rotating it into the ground. Another method involves using a split-spoon sampler driven into the ground to obtain a undisturbed soil core. Careful excavation with a soil core sampler can also help collect undisturbed soil samples.
How does salt get into the soil?
Salt can enter the soil through various natural processes, such as the weathering of rocks and minerals containing salt, seepage of saltwater from the ocean or from salt deposits underground, or through the use of fertilizers or de-icing salts that contain sodium chloride. Additionally, human activities like irrigation with salty water or improper disposal of industrial waste can also introduce salt into the soil.
Is salt harmful to the soil?
Excessive salt can be harmful to soil by disrupting the balance of nutrients and causing desiccation in plants. It can also hinder water absorption and reduce soil fertility. It is important to monitor and manage salt levels in soil to maintain healthy plant growth.
What method allowed soil to recover from?
Crop rotation is a method that can help soil recover from overuse. By alternating crops in a field, different plants can replenish nutrients in the soil, prevent soil erosion, and control pests and diseases, leading to healthier soil for future plant growth.
What is a method of renewing soil fertlity?
One method of renewing soil fertility is through crop rotation, where different types of plants are grown in succession to help replenish nutrients in the soil. Another method is using organic matter, such as compost or manure, to add nutrients back into the soil. Additionally, planting cover crops can help prevent erosion and add organic material to the soil when they are tilled back in.
How can we obtain potassium nitrate which is free of soil?
A simple method is to filter the aqueous solution; after this the solution is heated to obtain crystallized KNO3.
What are the method of collecting undisturbed soil sample?
One method is using a soil auger to collect a cylindrical sample by rotating it into the ground. Another method involves using a split-spoon sampler driven into the ground to obtain a undisturbed soil core. Careful excavation with a soil core sampler can also help collect undisturbed soil samples.
How we obtain pure potassium nitrate which is free of soil?
Pure potassium nitrate can be obtained by dissolving a source of potassium nitrate, such as KNO3 crystals, in water and then filtering the solution to remove any soil or impurities. The filtered solution can then be evaporated to dryness, leaving behind pure potassium nitrate crystals.
What do salt do to the soil?
Salt is a contaminant for soils because many plants doesn't accept too much salt in soil.
Are salt and soil together a mixture compound or element?
Salt and soil are together mixture of compounds.
How do you remove salt from plant soil?
To remove salt from plant soil, you can leach the soil by flushing it with water multiple times until the excess salt is washed out. Ensure proper drainage to prevent waterlogging, and consider repotting the plant with fresh soil if the salt concentration is very high. Additionally, you can test the soil periodically to monitor the salt levels.
Will ice melt faster in soil or salt?
salt
When salt is scaterred on the soil of a potted plant why does it die?
when salt is scattered on the soil of a potted plant why does it die
Method to separate soil and salt?
1st answer:filter the soil through filter paper 2nd answer: incorect information above new answer: If it is literally salt poured over the soil you could use a centrifuge. :) click the link : http://www.wisegeek.com/what-is-a-centrifuge.htm 3rd answer: Answer 1 is on the right track if the quantity is small. Use water to dissolve the salt then filter the solids (mud!) from the brine. At a larger scale there such as in the garden there is probably little you can do. Although wasteful of water, drenching the soil will dissolve the salt you can't simply scoop up, and the solution will leach down into the ground and eventually become harmless. If the ground is dry, scoop up the top layer of soil and salt, then dissolve and wash the salt away.
What is the pure substance in soil?
The main pure substance in soil is mineral matter, which includes minerals like clay, silt, and sand. These mineral particles make up the solid components of soil. Organic matter, water, and air also contribute to the composition of soil.
What is the presence of salt in topsoil called?
This is called soil salinity.Or the process of increasing salt in soil is called salinization
What kind of soil is in the salt water biome?
Saline Soil
