Question

KCl and I2 are both solids at room temperature. Which substance will dissolve in CCl4 and which substance will dissolve in H2O. Give an explanation for your choice ​

Answer 1

Answer:

I2 will dissolve in CCl4

KCl will dissolve in H2O

Answer 2

Answer:

KCl Dissolves in water and I2 Dissolves in H2O

The I2 molecules in iodine and the CCl4 molecules in carbon tetrachloride are both held together by weak intermolecular bonds. Similar intermolecular bonds can form between I2 and CCl4 molecules in a solution of I2 in CCL4.

Lattice energy of KCI is less than hydration energy of K+ and CL-. K+ and Cl-

get surrounded by water molecules and these ions remain separate and dissolved in water. So, KCl is easily soluble in water.
