Question

if Na+ is larger than MG + 2 ion and S-2 ion is larger than CL - Ion which of the following will be more soluble in water​

Answer 1

Answer:

Explanation:

Higher the lattice energy, lower the solubility. Out of the four combinations possible, the lattice energy of MgS (bi-bivalent ionic solid) is higher than those ofNa2S,MgCI22S,MgCI2 (uni-bivalent or bi-uni-valent ionic solids) and NaCl uni-univalent ionic solids and hence, MgS is the least soluble
