Sodium chloride is added before extracting the aqueous layer with dichloromethane (DCM) to enhance the separation of phases by promoting the salting-out effect, which reduces the solubility of organic compounds in the water and drives them into the organic layer. Magnesium sulfate acts as a drying agent that helps to break emulsions by absorbing water and reducing the viscosity of the aqueous layer, thereby facilitating the separation of the organic and aqueous phases. This combination improves the efficiency of the extraction process.
Aqueous magnesium chloride is not used to extract magnesium because the process requires a significant amount of energy to reduce magnesium ions to metallic magnesium. Electrolysis of molten magnesium chloride is the preferred method, as it effectively separates magnesium from chloride ions at high temperatures, allowing for the production of pure magnesium. Additionally, the high solubility of magnesium chloride in water complicates the extraction process, making it less efficient compared to other methods.
You would observe precipitation of magnesium hydroxide.

No. Magnesium oxide is not soluble in water. On contact with water it will form magnesium hydroxide.
Yes, MgCl2 can form an aqueous solution when it is dissolved in water. MgCl2 dissociates into magnesium (Mg2+) ions and chloride (Cl-) ions in water, forming an aqueous solution.
Magnesium chloride can exist as a solid, liquid, or aqueous solution depending on its physical state. Solid magnesium chloride is a crystalline substance, liquid magnesium chloride is a molten form, and aqueous magnesium chloride is a solution in water. It does not exist as a gas under normal conditions.

The compound formed when magnesium chloride is dissolved in water is magnesium chloride itself, represented by the formula MgCl2.
Magnesium chloride is a compound. It can dissolve in water to form an aqueous solution.
When magnesium chloride (MgCl₂) dissolves in water, it dissociates into its constituent ions. The reaction can be represented as: [ \text{MgCl}_2 (s) \rightarrow \text{Mg}^{2+} (aq) + 2 \text{Cl}^- (aq) ] This equation shows that solid magnesium chloride breaks down into magnesium ions and chloride ions in aqueous solution.
A precipitate is expected to form when an aqueous solution of sodium sulfate is added to an aqueous solution of barium chloride. This reaction results in the formation of insoluble barium sulfate, which appears as a white precipitate.
The difference in pH between the solutions is due to the hydrolysis of the chloride ions. In the case of magnesium chloride, magnesium ions hydrolyze in water to form acidic hydrogen ions, lowering the pH. Meanwhile, in sodium chloride, the sodium ions have minimal effect on pH, resulting in a neutral solution.
aqueous magnesium chloride is when magnesium oxide dissolves in hydrochloric acid. Aqueous means dissolved in water. ananya

Aqueous sodium chloride is also known as salty water.
You could use potassium, rubidium or caesium. However, there is no practical reason why you would do this. You'd have to do it in the melt, which would be hazardous, as all these metals react with water.
