Answer:
The supersaturated solution
it is a solution usually very sugary
excess solute
the supersaturated solution is a solution
where there is solute and solvent, there is always interaction
Explanation:
The supersaturated solutions are solutions where the solute is in excess, the solute is in constant interaction with the solvent and being in excess it precipitates to the bottom of the solution.
A supersaturated solution has a very high osmolarity.
The crystal structure of barium fluoride BaF₂ and magnesium fluoride MgF₂ is cubic and tetragonal lattice respectively.
There are difference between the cubic and tetragonal lattice of any crystal. For cubic lattice a = b = c and α = β = γ = 90⁰ and for tetragonal lattice a = b ≠ c and α = β = γ = 90⁰ (where a, b and c are the edge length of the lattice and α, β, γ angle of the crystal lattice).
The difference of the structure depends on the size of the ions present in the compound. In BaF₂, the ions are Ba²⁺ and F⁻. In MgF₂, the ions are Mg²⁺ and F⁻.
Although the size of the anion in both the crystal is same, there is a huge difference between the size of the cation, which affect the crystal lattice of the compound.
