Question

liF and csI are most insoluble in water​

Answer 1

Here is your answer.

CSI.

Lower is the hydration enthalpy lower is the solubility of salt. Hence CSI have lower solubility in water.

In CSI the constituent ions are Cs+ and I-.Both these ions are large in size as a result of which their hydration enthalpy is small.

LiF.

In this case the hydration enthalpy is very less. Hence LiF is insoluble in water.

Due to its low hydration energy and partial covalent and partial ionic character LiCl is soluble in water as well as acetone. In Lithium fluoride the lattice enthalpy is very high due to small size of fluoride ions.

I hope my answer is help you.

B brainly.

Answer 2

Cause of low hydration energy in Cscl and lif they are insoluable
