Ba2+ higher the charge, more is the hydration. Actually even i have that doubt,
but it serves well to remember that hydration enthalpies of gr 2 elements (ions) are larger than those of Gr 1 (except H).
which would you expect to have larger(more negative) value of hydration energy : K+ or Ba2+ ?
think it's K+ due to smaller size of K+,but answer given is Ba2+.Please verify.
