The order of solubility in water is NaClO4>KClO4 But solubility in water depends upon ionic character and KClO4 is more ionic than NaClO4 due to large size of cation But still not know how its solubility is less than NaClO4 Please help me regarding this matter.

Hiii 
Here anions are same so, compare the cations 
The cations are Na+ and K+, charges are same, so compare size. Na+ is smaller than K+ so NaClO4 is more soluble
Hope his helps.

Because of small size of Na+, it's have high hydration energy as compare to K+ and solubility increases with increasing in Hydration energy.
