Why does solubility of sulphates decrease down the group?

WebLattice enthalpy is governed by several factors - including the distance between the negative and positive ions. Where you have a big negative ion, this inter-ionic distance is largely controlled by the size of that negative ion. WebThis means that the lattice enthalpy is higher. In group 16, for example, the lattice energy for sodium salts of iodides and fluorides keeps going down as we move down the table. Conclusion. Ionization energy, Ionization enthalpy, Born-haber cycle and lattice enthalpy are 4 terms that we learnt about in this article. clip art hugs and lovesWebThis is because: A lattice energy is same but hydration energy decreases down the group. B hydration energy is same but lattice energy decreases down the group. C both lattice and hydration energy increase down the group. D decrease in lattice energy down the group is faster than decrease in hydration energy. Hard Solution Verified by Toppr clipart hugs friends
