In general, the solubility of a substance depends on not only the energetic factors we have discussed but also the temperature and, for gases, the pressure. The solubility of different compounds relative to each other in water. Question: Is B2 2-a Paramagnetic or Diamagnetic ? With most compounds, on descending the group, the hydration energy decreases more rapidly than the lattice energy: hence the compounds become less soluble as the metal gets larger. The solubility product constant for The solubility product constant for A: Ksp concept :Ksp : At normal temperature, if the solubility of a salt is 0.1mol / Lit then that salt Lets do an example: The solubility of Ag2CrO4 in water is 1.31 x 10-4 moles/L. However, solutes can be in any state: gas, liquid, or solid. Even if it is a weaker conjugate base, why didn't this happen?

None of the above silver is soluble. The other fluorides MF2 are are all almost insoluble. If we know that a substance is insoluble, it is likely that it would have excess solute, thus forming a precipitate. BeF2 is soluble in water due to evolution of large hydration energy, when it is dissolved in water, which is sufficient enough to overcome the lattice energy of the Berylium Flouride, as for a compound to be soluble in water, the lattice energy of the compound must be less than the hydration energy evolved upon dissolution in water. Note that a very small amount of BaF2 would dissolve but very little. . Exceptions Ag+, Pb2+, and (Hg2)2+- most sulfates are soluble. The sulphates of calcium, strontium and barium are insoluble, and the carbonates, oxalates, chromates and fluorides of the whole group are insoluble. In general, solutes will also be more soluble if the molecules in the solute are smaller than the ones in the solvent. The other fluorides MF2 are are all almost insoluble. Thus, Fe(OH)3, Al(OH)3, Co(OH)2 are not soluble. Question = Is SCl6polar or nonpolar ? What is Soluble and Insoluble ?
