Describe how water & mineral salts are taken into the root. (5marks)?

im guessing by root u mean plants..\nwell all plants absorb water and minerals through osmosis/diffusion.

NaCl extracted with water more than once to ensure that all particles of the soluble substane have been removed.\n\nHope this helps,\nUltimeaciax

Simple, just follow this process respectively. Since its one whole of a solution. Begin with distillation. This will get rid of the oil, sand+dirt and the salty water. \n\nDirt+sand - you could add water and then sieve the dirt and water. as for the dirt distilation.\n\nSalty water - you just need to heat the solution and distill the vapour to have your water other wise the salt will form crystals and loose water to the atmosphere thus nice dry sodium cloride crystals. \n\nHope you got answered....

boil water and add teaspoon of salt, pour into container and refrigerate for a day\npour out and wash container\nsmell should be done

You really need to give a little more information about what you are attempting to convert.  However, in very general terms you remove the sulfate, usually by making a solution containing your material basic.  You then form the hydrochloride salt by adjusting the pH back to the acid side via the addition of hydrochloric acid.\n\nPlease note, this process applies to the salt conversion of materials that are basic in nature and water soluable as their salt form.

Osmotic pressure refers specifically to the difference in the concentration of elements between two solutions.  If you place a semipermeable barrier between the two solutions, water will flow across that barrier until the concentrations are equal.\n\nIn this way, when you put a freshwater plant into salt water, the fresh water flows out from the plant through the cell membranes, which are semipermeable to water but not salt.\n\nThis osmotic pressure is actually how your kidneys work, to filter fresh water from the fluid you drink and leave a more concentrated solution behind.  See the links below for more details.

Add water to dissolve the salt.  Drain water and boil off.  Salt is now separated from sand.

http://www.biologyreference.com/Ve-Z/Water-Movement-in-Plants.html\n\nThe Cohesion-Tension Theory\nThe major mechanism for long-distance water transport is described by the cohesion-tension theory, whereby the driving force of transport is transpiration, that is, the evaporation of water from the leaf surfaces. Water molecules cohere (stick together), and are pulled up the plant by the tension, or pulling force, exerted by evaporation at the leaf surface.\n\nWater will always move toward a site with lower water potential, which is a measure of the chemical free energy of water. By definition, pure water has a water potential of 0 MegaPascals (MPa). In contrast, at 20 percent relative humidity, the water potential of the atmosphere is -500 MPa. This difference signifies that water will tend to evaporate into the atmosphere. The water within plants also has a negative potential, indicating water will tend to evaporate into the air from the leaf. The leaves of crop plants often function at -1 MPa, and some desert plants can tolerate leaf water potentials as low as -10 MPa. The water in plants can exist at such low water potentials due to the cohesive forces of water molecules. The chemical structure of water molecules is such that they cohere very strongly. By the cohesion-tension theory, when sunlight strikes a leaf, the resultant evaporation first causes a drop in leaf water potential. This causes water to move from stem to leaf, lowering the water potential in the stem, which in turn causes water to move from root to stem, and soil to root. This serves to pull water up through the xylem tissue of the plant.\nFrom Root to Leaf\nPlants have root hairs and often mycorrhizal fungi at the root surface, both of which serve to filter the soil water as it enters the plant. Mycorrhizae are symbiotic associations between plant roots and fungi. The root cells and mycorrhizal fungi both actively uptake certain mineral nutrients. Mycorrhizae can be particularly important for the uptake of phosphate. The active uptake of minerals by living cells of the root and the subsequent transfer of minerals to the xylem can result in positive root pressures, with water potentials above 0 MPa. This occurs only under certain conditions, such as at night or during rainstorms, when water loss from the leaves is minimal. Such positive root pressures disappear with the onset of leaf transpiration.\n\nWater molecules move from the soil into living cells of the root, and eventually into the transport cells of the xylem, known as tracheids and vessels. These xylem cells are dead and hollow, allowing rapid water transport. They also have hardened cell walls to help them resist the tendency to collapse as water is sucked through them. Both tracheids and vessels \n\n \nA drop of guttation, water extruded by a plant's root pressure, on a blade of grass. have pits on the sides of their walls, which include porous areas for side-to-side transport. Unlike tracheids, a vessel is composed of many cells stacked end to end, with perforations between cells, allowing for more efficient transport.\n\nThe long-distance transport of the water molecule occurs first within the xylem cells of the root, then the xylem of the stem and branch, and then into the xylem of a leaf midrib and vein. Driven by transpiration, the water molecule is pulled from the nonliving tracheids and vessels of the xylem in the living cells of the leaf mesophyll (middle layer) and to the surface of mesophyll cell walls. The water molecule then evaporates into a leaf inter-cellular air space and finally out of a stomatal pore and into the atmosphere. Though photosynthetic action consumes some water, only a small fraction of the water that travels through the plant is used directly for the photo-synthetic reaction, which occurs in leaf mesophyll cells. Instead, most water is lost by transpiration through the stomates.\nThe Role of Stomates\nLeaves of land plants are covered with a waxy cuticle that pr

First, it is spelled "deionize". \n\nde = remove\nion = charged particle\n\nSo, you are removing in ions from the water. An ion is a charged particle.  Sodium ion, Na+ or Chloride, Cl- are the most common ions in water. But you do not want them in your water in high concentration, so you deionize it.\n\nThe process is best performed in two steps.  First you would boil the water and capture the steam, allow the steam to turn back into liquid water, then repeat the process.\n\nBut this process only gets you so far. If you want the water to be truly deionized, and able to be used in a chemistry lab you will need to run it thru a resin chamber.\n\nResin or resin beads are very very small plastic like beads that have microscopic tunnels running thru them. Then inside of the tunnels have molecules that attract ions. Or type of resin will attact the positive ions another type will attract negative ions. All resin chambers have both types of resin.\n\nRob

Sea salt melts it quickly.\n\n\nPeace

center up to after then you add salt to main, I but not knowif my then old......so, hope that answers your question. Glad to be of assistance.

mix it...let NaCl dissolve in water...then let the mmixture evaporate or perhaps bring the mixture into a boil 'til you can see the formation of crystals...   try it... i've encountered such experiment in my chemistry class... im not quite certain of the procedures though...it's two years ago...cant remember it well...^_^

What I think you want is how do you split ionic compounds into ions.  Solutions!\n\nWhen you have an ionic compound, like salt (NaCl) you can split the compound into its ions by dissolving it in water.\n\n     (H2O)\nNaCl(s) ----->  Na+(aq) + Cl-(aq)\n\nThe (s) means solid, cause salt is a solid.  When you put it in water, it changes from (s) to (aq) which means aqueous.  Aqueos basically means that the substance is an ion in a water solution.\n\nHope this helps.

raising the temperature. like with a saturated solution of salt-water, if you reise the temperature the water will take in more salt. it's the same with other thing too.
