Saline hydrides can remove traces of water from organic compounds because :

1. They react with water to form a metal hydroxide along with the liberation of oxygen gas.
2. They react with water to form a metal hydroxide along with the liberation of hydrogen gas.
3. They react with water to form a metal carbonate along with the liberation of oxygen gas.
4. They react with water to form a metal carbonate along with the liberation of hydrogen gas.
