Among LiF and LiI, which is more soluble in water and why ?

Explanation

To determine which compound, LiF (lithium fluoride) or LiI (lithium iodide), is more soluble in water, we can follow these steps:

### Step 1: Identify the Nature of the Compounds
Both LiF and LiI are ionic compounds because they are formed from the reaction of lithium (Li), a metal, with a halogen (F or I).

**Hint:** Remember that ionic compounds are formed from metals and non-metals, and they typically have high melting points and solubility in polar solvents like water.
