Question

In which of the following MgCl2 is soluble?
A) Petrol B) Acetone C) Kerosene D) Water

Answer 1

Magnesium chloride is soluble in water.

• We know that the chemical formula of the compound magnesium chloride is $MgCl_2$.
• The compound Magnesium chloride is highly soluble in water.
• On reaction with water, it forms a base called magnesium hydroxide.
• The reaction of magnesium chloride and water is given as-
• $MgCl_2+2H_2O\rightarrow Mg(OH)_2+2HCl$
• In this reaction, we can see that one mole of magnesium chloride reacts with water to form magnesium hydroxide base along with two moles of hydrochloric acid.
• Thus, the correct option is D.
