What happens when sulfuric acid is added to magnesium?
Magnesium reacts with dilute sulphuric acid to form magnesium sulphate and hydrogen gas. This is a single displacement reaction and also exothermic.
What is the purpose of using sulfuric acid?
The major use of sulfuric acid is in the production of fertilizers, e.g., superphosphate of lime and ammonium sulfate. It is widely used in the manufacture of chemicals, e.g., in making hydrochloric acid, nitric acid, sulfate salts, synthetic detergents, dyes and pigments, explosives, and drugs.
How are magnesium sulfate crystals formed?
Magnesium sulfate-7-water, MgSO4. 7H2O, crystals are obtained by evaporation. You can make magnesium sulfate-7-water in the laboratory by reacting magnesium oxide with dilute sulfuric acid.
Which is the acid required for the preparation of magnesium sulphate?
Magnesium oxide is prepared by igniting magnesium hydroxide (obtained from sea water) or ignition of magnesite ore (consists of MgCO3). The magnesium oxide formed is then reacted with sulfuric acid to produce magnesium sulfate.
Is sulfuric acid and magnesium endothermic or exothermic?
As the reaction is exothermic, students will need to design their experiment very carefully if they wish to investigate the effect of temperature on this reaction.
Which process is used for the preparation of sulphuric acid?
Contact process
Contact process is used for the manufacture of sulphuric acid. The various steps in the Contact process are as follows: Production of sulphur dioxide.
Is used to prepare sulphuric acid?
Sulfuric acid is prepared industrially by the reaction of water with sulfur trioxide (see sulfur oxide), which in turn is made by chemical combination of sulfur dioxide and oxygen either by the contact process or the chamber process.
How do you make crystals of magnesium sulfate from magnesium oxide and sulfuric acid?
Equation for reaction:
- MgO + H 2SO 4 → MgSO 4 + H 2O.
- or Mg[OH] 2 + H 2SO 4 → MgSO 4 + 2H 2O.
- or MgCO 3 + H 2SO 4 → MgSO 4 + H 2O + CO 2
- or Mg + H 2SO 4 → MgSO 4 + H 2
Why is magnesium sulfate used?
Magnesium is a naturally occurring mineral that is important for many systems in the body especially the muscles and nerves. Magnesium sulfate also increases water in the intestines. Magnesium sulfate is used as a laxative to relieve occasional constipation.
What is the boiling point of magnesium sulfate?
330.00 °C.

Why is magnesium sulfate exothermic?
Its all a matter of breaking bonds (endothermic) and making bonds (exothermic). It requires energy (heat) to break up the magnesium sulphate lattice (solute) into individual ions, so that process is endothermic. Therefore the overall reaction (in this case) is endothermic and the solution cools.
