Explain the entropy of hydration becomes additional negative

Reference no: EM13674423

The entropy of hydration becomes additional negative from Na+ to Mg2+ to Al3+ though the coordination number is probably 6 in each case. Account for the trend in disorder.
S?298 (J mol-1 K-1): Na + (aq), 60.3; Mg2 + (aq), -138; Al3 + (aq), -322.
