Question

Cacl2 is highly soluble in water while caf2 is insoluble in water

Answer 1

hey buddy !! here's your answer...

➡️CaF2 has high lattice energy.. higher than its hydration energy while CaCl2 lattice energy is less...
✔️ hence CaCl2 is soluble as its hydration energy overcomes lattice energy

hope it helps !! ❤️✌️

Answer 2

Concept:

Dissolvability is characterized as the greatest measure of a substance that will break down in a given measure of dissolvable at a predefined temperature. Dissolvability is a trademark property of a particular solute-dissolvable mix, and various substances have significantly contrasting solubility. In science, dissolvability is the capacity of a substance, the solute, to shape an answer with another substance, the dissolvable. Insolubility is the contrary property, the failure of the solute to frame such an answer.

Given:

Here it is given that  $CaCl_2$  is highly soluble in water.

Find:

We have to find while   $CaCl_2$  is highly soluble in water but why $CaF_2$  is insoluble in water.

Solution:

According to the question,

• $CaF_2$ has high lattice energy.. higher than its hydration energy while $CaCl_2$ lattice energy is less...

Hence $CaCl_2$ is soluble as its hydration energy overcomes lattice energy.
