Answer 2

The substance that do not contain water of crystallization among the four substances listed are common salt and washing soda.

• Blue vitriol is the common name for penta hydrate copper sulfate.Its formula shows it to have five water of crystallization but it has only one water of crystallization, since the rest four water molecules are bonded coordinately to the copper ion.

• Deca hydrated sodium sulfate is called Glauber's salt.
• Washing soda crystals consists of sodium carbonate.
