You can evaporate, or distill off the water.  Then you'll get the CuSO4, along with any non-volatile impurities that may be present.  Or you can do a recrystalization.  You boil the solution until the CuSO4 just starts to crystalize out.  Then you let the solution cool.  As it cools, the solubility of the salt decreases, and more & more of it crystalizes.  When cooling, you may end up with a super-saturated solution, instead of crystals being formed.  In that case, scratching the inside of the beaker with a glass rod will initiate the crystalization process.  With recrystalization, the product is also purified.

25cm3 of a 4M solution of CuSO4 contains 25/1000 x 4 M CuSO4 = 0.1M\n\n! mole of CuSO4 weighs 160g (Cu = 64 + S=32  + O4 = 64)\n\nSo   0.1 Mole weighs  16g. This is how much anhydrous solid is needed. \nHowever copper sulphate usually comes as crystals and 1 mole of this weighs 250g ( + 5H20 = 90) so to make a 0.1 molar solution from crystals you need 25g CuSO4. 5H2O

You know, I answered exactly the same question not 2 days ago.\n\nAnhydrous copper sulfate and water would be the easiest two. \n\nYou can buy copper sulfate at any good garden supply shop and most larger hardware stores. The copper sulfate usually sold is hydrated, and is already blue in colour.\n\nYou can make it anhydrous by putting it the oven, uncovered on a sheet of tin foil at 160oC or hotter. You will know when it has become anhydrous beause it goes white. This is quite safe to do in your kitchen oven, all you are doing is driving off the water. No nasty fumes or residues are produced.\n\nStore the crystals in an airtight jar to stop them absorbing water from the air. When you are ready add some water to a few crystals they will retrun to their original blue colour.\n\nThe other possibility is to manufacture your own cabbage indicator. That will make a bluish purple colour when mixed with baking soda. I've included a link with instruction on how to do this.

To purify (separate) the product you want from impurities. For example, if you wanted to separate a mix of alcohol and water, you would use the distillation flask along with a heating mantle (like a Bunsen burner, but designed for flasks) to heat the mixture; because alcohol has a lower boiling point than water, it would evaporate faster and re-condense in the collection flask, leaving water in the distillation flask.

Distillation is a method used to seperate substanced based on their boiling points.\n\nIf you have a mixture of say....water and sand, one way to seperate them would be to evaporate away the water, leaving the dry sand behind.  This also works for other things, like a solution of water and alcohol.  Since alcohol has a lower boiling point (meaning that it has a higher vapor pressure at a given temperature than water), it will evaporate quicker than water when you heat the solution.\n\nWhen you lower the pressure above a liquid, the liquid boils at a lower temperature.  A liquid will boil when its vapor pressure eqauls the pressure above the liquid, so if you lower pressure, you lower its boiling point.\nWhen you lower the pressure substancially (like with a vacuum) liquids will boil much easier (some even at room temperature), meaning that you do not have to heat them up quite as much in order to boil them.

Copper sulfate will only partly dehydrate at 120oc. You will need to set your oven to 160oC or higher to create anhydrous copper sulfate.

Well, I do not know that syllabus.  You will need to sift useful answers.\n\nI would use:\n\ndifferent solubility in solvents\ndifferent boiling points\nrecrystallise one out of a mixed solution\n\nYou might be at too junior a level to know about ion exchange resins, and other chromatography techniques.

Dissolved mineral salts produce ions in most tap water.  The process of distillation evaporates pure water as steam and then recondenses it into liquid water as it cools.  The minerals and other impurities are left behind, so there won't be any ions in distilled water.

Fe(NH4)2(SO4)2 .6H2O is highly insoluble in non polar organic solvents like chloroform, dichloromethane, etc. Might be slightly soluble in alcohols. Better you dissolve it in minimum amount of water (make highly saturated solution) and add drop by drop alcohol  in a period of time and keep aside without shaking. Crystals will grow slowly.\nIt might be helpful.

Distillation. Put sugar water in a crucible or beaker and heat over a burner. When all the water has evaporated, the sugar will be left. If you are actually going to carry out this experiment, be careful to not burn the sugar after the water has evaporated, unless you don't mind throwing out the beaker or doing some serious scrubbing.

We can solve this using a system of equations.\n\nLet x be the volume of the 25% solution. Let y be the volume of the 60% solution.\n\nThe sums of the volumes must total 140 ml:\n\nx + y = 140.\n\nThe mass of CuS04 in the desired solution must equal the amounts added through the use of both solutions.\n\n30 percent of 140ml gives 42 ml of "pure" copper sulfate solution.\n\nThe 25% solution would contribute .25x of "pure" copper sulfate solution. The 60% solution would contribute .60y of "pure" copper sulfate solution, so:\n\n0.25x + 0.60y = 42.\n\nHere is the system:\n\nx + y = 140\n0.25x + 0.60y = 42\n\nThere are many different ways to solve the system. I'll use substitution here:\n\nx + y = 140, so y = 140 - x\n\n0.25x + 0.6(140 - x) = 42\n0.25x + 84 - 0.6x = 42\n-0.35x = -42\nx = 120\ny = 20\n\nSince x is the amount of 25% solution and y is the amount of 60% solution, we need 120 ml of 25% solution and 20 ml of 60% solution.\n\nThis appears to match your answer!

Copper can be extracted from its ore by:\n\n1. Traditional mining\n (a) underground - sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore.\n(b) open pit  - 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers.\n\n2. Leaching\n\nThe ore is treated with dilute sulphuric acid. This trickles slowly through the ore dissolving copper to form copper sulphate. The copper is recovered by electrolytic refining. Advantages of this process are:\n\n    * much less energy is use than in traditional mining\n    * no waste gases are given off\n    * it can be used on ores with as little as 0.1% copper - for this reason, leaching extraction is growing in importance.\n\nA typical ore contains only 0.5% to 2.0% copper. \n\nConcentrating the ore :-\n\nThe ore is crushed, ground and then enriched (concentrated) by Froth Flotation.\n\nThe powdered ore is mixed with a special paraffin oil which makes the copper mineral particles water repellent. It is then fed into a bath of water containing a foaming agent which produces a kind of bubble bath.\n\nWhen jets of air are forced up through the bath, the water repellent copper mineral particles are picked up by the bubbles of foam. They float to the surface making a froth. The unwanted waste rock (gangue) falls to the bottom and is removed.\n\nThe froth is skimmed off the surface and the enriched ore (mainly the copper mineral) is taken away for roasting. The mixture of water, foaming agent and paraffin is recycled.\n\nAfter this stage the enriched ore now contains about 25% copper by mass.\n\nAlso check other details at  -\n\nhttp://en.wikipedia.org/wiki/Copper_mining
