Are salts containing sodium soluble or insoluble?

Explanation:
Salts containing sodium are soluble in water. This follows the general pattern that salts with alkali metal cations (like sodium) dissolve because water, a polar solvent, surrounds the Na+ ions and the counter-ions, breaking the solid lattice. The process releases energy from hydrating the ions, which helps overcome the lattice energy of the salt, so it dissociates into Na+ and the anion in solution. This is true for common sodium salts such as sodium chloride, sodium nitrate, sodium sulfate, and sodium carbonate. They don’t chemically react with water; they simply dissolve by dissociating into ions.
