At 25 °C the following constants apply:
• CaF₂, Kₛₚ = 3.9 × 10⁻¹¹
• AgCl, Kₛₚ = 1.8 × 10⁻¹⁰
• BaSO₄, Kₛₚ = 1.1 × 10⁻¹⁰
• HF, Kₐ = 6.6 × 10⁻⁴
The pH of the solution is adjusted to 2.0. Calculate the molar solubility of each salt at this pH and rank them from most soluble to least soluble, using the format “_____ > _____ > _____.”
