Sand is not a pure substance - it can be a mixture of almost countless compounds. Sand and water is a mixture although, chemically speaking, the term mixture tends to be reserved for mixtures of components that are the same phase.
it depends on the source of the sand. If it is sterilized sand from a building supply source wouldn't it be pure?
Filtrate is considered pure because it is a liquid that has been separated from insoluble solid particles through the process of filtration. Filtration allows for the removal of solid impurities, leaving behind a relatively clear and particle-free liquid. However, it is worth noting that while filtrate is generally pure in terms of solids, it may still contain dissolved impurities or contaminants that are present in the original solution.
Because sand is a solid and will be retained by the filter, whereas water is a liquid which will pass through the filter. The sand is not soluble in the water so it will remain a solid, rather than dissolving.
yes
The filtrate is the liquid that is left after you filter something -- the liquid that is now "missing" the solid that was filtered out.For instance, if you are making drip coffee, it is the coffee beverage (the coffee grinds are called the "filtrand"). If you are removing sand from water, it is the water that is pure (again, the removed sand would be the filtrand).
FilteringThe sand will be caught by the filter paper as residue and the water will come out the bottom of the filter funnel as the filtrate.
A filtrate doesn't contain insoluble substances but can contain soluble substances.
Weigh each sample and then make a solution of coffee, sand and water. First of all, we have to filter the solution with the help of filter paper so all the water will pass through the paper and as a filtrate we will have coffee and sand. Take the filtrate and let it dry. Secondly, once the filtrate is dry take a strong magnet and scan across, underneath the filter paper. This will separate all the sand on one side of the filter paper. Finally, record the mass of each component after the experiment.
Simply filtration. In these types of separation questions, please think of the different properties of the substances you want to separate. In this case, Sand doesn't dissolve in water, so if you filter the mixture, you will get sand as the residue and water as the filtrate.
no
Dissolve the whole salt in a warm water, then filter it out. By evaporating the filtrate, we shall get pure salt. The impurities will left on the filter paper(as these are insoluble in water).
filtrate sand is a filtrate it stays behind
As the filtrate goes down the hypertonic interstitum of the renal medulla, water leaves the filtrate into the interstitum. As such, the water concentration in the filtrate decreases.
Because you mixed sand and water together in the beaker.
