Write two properties of alkali metals salts of oxo-acids.

Explanation

**Step-by-Step Solution:**

1. **Identify the Subject**: The question asks for two properties of alkali metal salts of oxo-acids. Alkali metals are found in Group 1 of the periodic table, which includes lithium (Li), sodium (Na), potassium (K), rubidium (Rb), and cesium (Cs).

2. **Understanding Oxo-acids**: Oxo-acids are acids that contain oxygen, hydrogen, and another element (the central atom). Alkali metals can form salts with these oxo-acids.

3. **Property 1 - Solubility**: One of the key properties of alkali metal salts of oxo-acids is that they are generally soluble in water. This solubility is due to the ionic nature of these salts, which allows them to dissociate in water, forming ions.
