question 5 (1 point)
what is a hydrate?
salt that is thermally decomposed
dehy dration of a salt
a water molecule
an ionic compound containing water molecules that are bound weakly to the metal
ionic compound that does not contain any water molecules

Explanation:

A hydrate is defined as an ionic compound that has water molecules weakly bound to the metal ions within its structure.

• "Salt that is thermally decomposed" is incorrect as it doesn't define a hydrate but rather a process that can be done to a hydrate.
• "Dehydration of a salt" is a process (removing water from a hydrate), not the definition of a hydrate.
• "A water molecule" is too simplistic; a hydrate is a compound, not just a single water molecule.
• "Ionic compound that does not contain any water molecules" is the opposite of a hydrate.

Answer:

an ionic compound containing water molecules that are bound weakly to the metal
