Magnesium chloride and silver nitrate solutions are mixed. Given that a precipitation reaction occurs, the precipitate is likely to be:Group of answer choicesChloride nitrateMagnesium nitrateSilver chlorideSilver magnesium
Solution
When magnesium chloride (MgCl2) and silver nitrate (AgNO3) are mixed, a double displacement reaction occurs. In this reaction, the cations and anions switch places, resulting in the formation of two new compounds.
The reaction can be represented as follows:
MgCl2 (aq) + 2AgNO3 (aq) -> 2AgCl (s) + Mg(NO3)2 (aq)
The products of this reaction are silver chloride (AgCl) and magnesium nitrate (Mg(NO3)2).
However, not all products will remain in solution. Silver chloride (AgCl) is insoluble in water and will therefore precipitate out of the solution.
So, the precipitate is likely to be Silver chloride.
