Question

3. Which of the following is most soluble in
water?
(a) CsCIO4
(b) NaCIO,
(c) KCIO
(d) LICIO​

Answer 1

$\huge\boxed{\underline{\mathcal{\red{A} \green{N } \pink{S } \orange{W } \blue{E } \pink{R }}}}$

(d) LiCIO4

As hydration energy is size dependent, as size increases hydration energy decreases so LiClO4

is more soluble in water than NaClO4 as it's hydration energy is higher due to smaller size of Li ion.
