Question If we slowly add a solution of mercury(II) ions to a solution of aqueous halide ions with roughly equal concentrations, a precipitate will form. Explain what the precipitate will consist of initially. Select the correct answer below: O The initial precipitate will consist of a single compound HgX2, where X is the halogen for which HgX₂ has the smallest Ksp O The initial precipitate will consist of a single compound, HgX2, where X is the halogen for which HgX₂ has the largest Ksp. O The initial precipitate will consist of a mixture of halide compounds of the form HgX₂, with mole fractions proportional to their respective Ksp values. O The initial precipitate will consist of a mixture of halide compounds of the form HgX, with mole fractions inversely proportional to their respective Ksp values.
