All; Albums; Appearances; Awards; In Performance; Press; Uncategorized Be(OH) 2 dissolves in strongly alkaline solutions. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms. Beryllium is found in bertrandite, beryl, chrysoberyl, phenacite, and many other minerals. And for a compound to be soluble it's lattice enthalpy should be low and it should decrease more … Elementary lead does not dissolve in water under normal conditions (20 o C, and pressure = 1 bar). Since, Its insoluble(less soluble), there are two seemingly correct explanations here-(1) high lattice energy (2) high hydration energy. Ammonium & Alkali ONLY. Yes it is insoluble in water because it has high lattice enthalpy and it's hydration enthalpy decreases more rapidly than lattice enthalpy on dissolving in water.
