Answer :
Final answer:
The process to purify the magnesium chloride solution of its contaminants involves a series of steps starting with filtration to remove the dirt, followed by evaporation to remove the ethanol. Crystallization will then take place, concentrating the solution to form solid crystals of magnesium chloride. Lastly, additional filtration and drying will be done to separate the crystals and dry them.
Explanation:
To obtain dry crystals of magnesium chloride from a solution contaminated with ethanol and dirt, a purification method should be applied. One possible method involves the following steps:
- Filtration - to remove large dirt particles.
- Evaporation - to remove ethanol, which has a lower boiling point than water.
- Crystallization - to concentrate the magnesium chloride solution to the point that it begins to form solid crystals.
- Filtration and Drying - to separate the crystals from the solution and dry them out.
This process will leave you with dry, purified crystals of magnesium chloride.
