Nitrate salts are ...?

Explanation:
Nitrate salts dissolve in water. The NO3− ion forms strong interactions with water molecules, and the lattice energy of many nitrate salts is not large enough to prevent dissolution, so the salts separate into ions in solution. This means aqueous nitrate solutions contain both the nitrate ion and the accompanying cation. They don’t typically decompose in water under ordinary conditions. So the correct description is that nitrate salts are soluble in water.
