Why does copper sulfate solution turn clear and magnesium develop a copper coating?
Redox! The magnesium is reducing the copper while the copper is oxidizing the magnesium. In other words, magnesium is giving electrons to the copper to bring the copper back to its metallic form while the magnesium is leaving the metal to be part of the solution as magnesium sulfate, which is colorless.
What else can I help you with?
How could a solution of magnesium sulfate and water be separated into its starting substances?
The solution of magnesium sulfate and water can be separated by a process called evaporation. The solution is heated until the water evaporates, leaving behind the solid magnesium sulfate. The remaining magnesium sulfate crystals can then be collected and the water can be condensed back into a liquid form through condensation.
How many grams of magnesium sulfate are in 300ml of a 120 magnesium solution?
To find the grams of magnesium sulfate in a 300 mL solution with a concentration of 120 mg/mL, you can multiply the concentration by the volume of the solution. This is calculated as follows: 120 mg/mL × 300 mL = 36,000 mg. To convert this to grams, divide by 1,000, resulting in 36 grams of magnesium sulfate in the solution.
How could you separate a heterogeneous mixture of Styrofoam beads sand and magnesium sulfate?
To separate a heterogeneous mixture of Styrofoam beads, sand, and magnesium sulfate, start by adding water to the mixture. The magnesium sulfate will dissolve in the water, while the Styrofoam beads and sand will not. You can then filter the mixture to separate the undissolved Styrofoam and sand from the dissolved magnesium sulfate solution. Finally, evaporate the water from the magnesium sulfate solution to recover the salt.
Is there an efficient method for obtaining pure magnesium from magnesium sulfate?
Yes, pure magnesium can be obtained from magnesium sulfate through a process called electrolysis. The magnesium sulfate is dissolved in water to form a solution that is then subjected to electrolysis, which involves passing an electric current through the solution to separate out the magnesium. This method is commonly used in industrial settings to produce pure metallic magnesium.
What would be need to do to produce solid magnesium sulphate?
To produce solid magnesium sulfate, you can start by reacting magnesium oxide (MgO) or magnesium hydroxide (Mg(OH)₂) with sulfuric acid (H₂SO₄). The reaction produces magnesium sulfate (MgSO₄) and water as a byproduct. To obtain solid magnesium sulfate, the resulting solution can be evaporated to remove excess water, allowing the magnesium sulfate to crystallize. The crystals can then be filtered and dried to yield solid magnesium sulfate.
What happens when you add iron to magnesium sulfate?
When iron is added to magnesium sulfate, a displacement reaction occurs where the iron displaces magnesium from the sulfate compound. This results in the formation of iron sulfate and magnesium metal as products. The iron sulfate dissociates into iron ions and sulfate ions in solution.
What would happen if you added iron to a solution of magnesium sulphate?
If you add iron to a solution of magnesium sulfate, a displacement reaction would occur, where the iron would displace the magnesium in the sulfate compound. This would result in the formation of iron sulfate and magnesium metal.
Does magnesium ribbon in copper sulfate solution produce a gas?
Yes, when magnesium ribbon is added to copper sulfate solution, a reaction takes place where magnesium displaces copper from the solution. This reaction produces magnesium sulfate and elemental copper. No gas is formed during this reaction.
What ions are in MgSO4?
Magnesium sulfate (MgSO4) dissociates into magnesium ions (Mg^2+) and sulfate ions (SO4^2-) in solution.
Is the solution of epsom salts prepared by dissolving magnesium sulfate heptahydrate in water is added to a solution containing sodium lauryl sulfate will a precipitate form?
Yes, a precipitate may form because magnesium sulfate heptahydrate contains magnesium ions which can react with the sulfate ions from sodium lauryl sulfate to form insoluble magnesium sulfate. This reaction can result in the formation of a white precipitate.

Will magnesium sulfate react with magnesium?
No, magnesium sulfate will not react with magnesium because magnesium sulfate is a salt that dissolves in water to form magnesium ions and sulfate ions. Pure magnesium does not react with magnesium sulfate.
Is MgSO4 7H2O acidic in solution?
Magnesium sulfate heptahydrate (MgSO4·7H2O) does not show acidic properties in solution as it dissociates into magnesium ions and sulfate ions. These ions do not contribute to acidity in the solution.
