In which of the following aqueous solutions would you expect PbCl2 to have the lowest solubility? a. 0.020 M KCl. b. 0.020 M BaCl2. c. 0.015 M PbNO3. d. pure water ... Web2 feb. 2024 · When strong acid is added to a saturated solution of CaF 2, the following reaction occurs: H + (aq) + F − (aq) ⇌ HF(aq) Because the forward reaction decreases the fluoride ion concentration, more CaF 2 dissolves to relieve the stress on the system. The net reaction of CaF 2 with strong acid is thus CaF2 ( s) + 2H + (aq) → Ca2 + (aq) + 2HF(aq)

Web2 feb. 2024 · Oxides of metallic elements are generally basic oxides, which either react with water to form a basic solution or dissolve in aqueous acid. In contrast, oxides of … Web8 mei 2010 · The question asks in what solution will CaF2 be least soluble? So the least soluble solution is one that already has some Ca or some F in it. The equation is CaF2 -> Ca^2+ + 2F^-. So Ksp = (Ca^2+)* (F^-)^2. Notice F- is squared so it has a higher impact. Choice 5 has none of them so CaF2 will dissociate in it the best. immersivemath 中文

In which aqueous system is PbI2 least soluble? a. Web23 apr. 2024 · In the situation of CaF2, Calcium is a group 2 metal and is most of the time not soluble and fluoride is not part of the soluble halogen group. So, most likely CaF2 cannot exist in an aqueous solution because neither of the elements are soluble so CaF2 will always exist as a solid inside of an aqueous solution. Share.
