Resolved Question: Help with a chemistry experiment?

Hi, I'm currently doing a chemistry experiment for my Assignment. We have to find an experiment that includes extracting a certain substance and I chose to extract Magnesium. I've found an experiment already but it leaves me with Magnesium Chloride instead of pure Magnesium. Please Help, I'm desperate! I don't mind if you give me a new experiment or just give me ways on how to extract the chloride from the magnesium, I just need this A.S.A.P.! Please help! This is my current experiment: Magnesium (Mg) exists in sea water as ions of magnesium. It's typically extracted from sea water on an industrial scale in a procedure known as the Dow Process. Magnesium chloride is used in the manufacture of fire-resistant materials, paper and textiles. It's also a common dicing agent and a precursor in the production of magnesium metal Step 1: Add slaked lime [Ca(OH2)] to sea water. The magnesium ions (Mg) in the sea water will combine with the slaked lime to form magnesium hydroxide [Mg(OH)2] and calcium. Magnesium hydroxide is a solid that will fall to the bottom of the solution as a precipitate and the calcium will remain in the solution as ions. The following equation shows this reaction: Mg + Ca(OH)2 ' Mg(OH)2 + Ca. Step 2: Separate the magnesium hydroxide from the sea water and add two moles of hydrochloric acid (HCl) for every mole of magnesium hydroxide. This reaction will form a solution of magnesium chloride in water. The following equation shows this reaction: Mg(OH)2 + 2 HCl ' MgCl2 + 2 H2O. Step 3: Add four moles of water to the magnesium chloride solution for every mole of magnesium chloride. The following equation shows this reaction: MgCl2 + 2 H2O + 4 H20 ' MgCl2 + 6H20. Step 4: Allow this solution to crystallize as magnesium chloride hexahydrate (MgCl2.6H20). Step 5: Store magnesium chloride as magnesium chloride hexahydrate. Pure magnesium chloride is difficult to store because it absorbs water extremely readily. Magnesium chloride hexahydrate may be dehydrated to magnesium chloride when needed by exposing it to hydrogen chloride gas How to make seawater Home uses of seawater include such things as aquariums, holistic treatments and agriculture. Seawater is inexpensive and simple to produce. According to the Seafriends Marine Conservation and Education Center, seawater is a combination of salts mixed with water and gases. While the composition of seawater varies by geographic location, mixing sea salt with tap water most accurately duplicates it at home. Sea salt contains minerals directly from the sea and tap water contains abundant natural minerals like calcium. Step 1: Determine the quantity of seawater you wish to produce. Step 2: Pour the tap water into a mixing container that is large enough to accommodate the quantity of seawater you are making. Allow the water to settle for approximately 10 minutes and come to room temperature. Step 3: Add the sea salt to the water, stirring slowly until completely dissolved. According to Sir Francis Drake High School, you will need approximately 35 grams of sea salt per liter of water or approximately 4 oz. of sea salt per gallon of waterThis is not what I'm giving in, the teacher wanted the specific method, we didn't have to change anything about it. The report will we written separately. more

Compared to another magnesium product, their 'true food' magnesium might enable the body to absorb 80% of the 100mg where as another brand might only provide 20% absorption. This would mean that their 'true food' product is 4 times more effective. You could equate this to the tablet being comparable to a 400mg tablet because you would have to take that much of the other 'brans' to get the equivalent benefit. However, as effective as 'true food' tablets are, there still is only physically 100mg in the tablet, therefore surely my body would be getting 80mg of magnesium? So, surely I still need to take the actual mg dosage for the RDA - 350mg or 7 of their 'true food' tablets. Am I missing something? They are adamant that a 50mg is the same as a 200mg... more

Resolved Question: Need help editing this paper for english errors :D (long)?

Irrigation is an alternative and artificial way of transporting water to the soil. Irrigation is often used in dry areas due to the lack of precipitation. One can irrigate a farmland by either using surface irrigation, drip irrigation, or sprinkler irrigation. Sprinkler irrigation is when you water the soil and planets by means of using a sprinkler. Drip irrigation is done by using pipes to transfer the water directly to the soil. Surface irrigation is done by digging certain parts of the farm land and using the force of gravity to spread the water around. Metallic salts are basically salts but they have at least one metal element in the compound. Salts are formed by the reaction of an acid and a base. For example, the base CuO reacts with the acid H2SO4 to produce Cu2SO4 (salt) and H20 (water). This is a classic example of a metallic salt. Naturally, only metallic salts exist but scientist can make non-metallic salt by forcing reactions. One example of this is Ammonium Chloride. NH3 + HCl → NH4Cl. Not all metallic salts are harmful to the environment. Some are ecosystem friendly such as cupric chloride. However metallic salts that are harmful are very dangerous and can kill animals and plants in an instant. Other examples of metallic salts are zinc sulfate, sodium chloride, and barium dichloride. Like metallic salts, carbonates also pose irrigation problems to farmlands. However unlike metallic salts they are formed with carbonic acid as opposed to a hydroxide acid. Carbonic acid is actually carbon dioxide dissolved in water (H2CO3). An example of this is calcium carbonate (CaCO3) where carbon dioxide (CO2) and calcium oxide (CaO) react to form calcium carbonate. Other examples of carbonates are sodium carbonate (NaCO3) and potassium carbonate (K2CO3). Potassium carbonate is soluble in water but insoluble in alcohol. Since potassium carbonate dissolves in water, it will dissolve in irrigation water which will make it very hard to separate the potassium carbonate from the H2O. One of the metallic salts that damages a farmland is copper (2) sulfate. Copper sulfate damages the plants indirectly by making the moist soil very dry. Since many plants only survive in moist soil then they will die due to lack of nutrition. The worst type of irrigation to use with copper sulphate is the water drip irrigation since the water goes directly to the root of the plants and soil. The main problem with copper sulphate is not the copper itself but rather the sulphuric acid within the compound. Sulphuric acid is very strong in terms of reactivity and structures of the molecules within Cu2SO4.Even worse is the fact that it goes unnoticed since it’s a colorless, odourless, and a clear dissolved liquid within the water that is about to be irrigated. Other metallic salts that pose problems to irrigation are anything that reacts with sulphuric acid. All carbonates and bicarbonates are a danger to the growth of the plant. Unlike the metallic salts, carbonates don’t have a specific element that harms the plant. All carbonates and bicarbonates with a few rare exceptions stop the growth of the plant. Bicarbonates and carbonates ions combine with the calcium and magnesium in the soil which poisons the roots of the plants. In order to solve the problems posed by metallic salts and carbonates, you can either use expensive equipment to separate the salt from the water or you can add gypsum when soils have low calcium.
