Question

Which of the following salt contain interstitial water molecule in it?

Options

• \[\ce{BaCl2.2H2O}\]

• \[\ce{[Cu(H2O)2(NH3)5]Cl2}\]

• \[\ce{CuSO4.5H2O}\]

• \[\ce{[Cr(H2O)5]^3+.3Cl^-}\]

Answer 1

\[\ce{BaCl2.2H2O}\]

Explanation:

Interstitial water molecules can be found in \[\ce{BaCl2.2H2O}\] salt. Between the first and second solvation shells, water molecules are primarily trapped. It can be found in the crystal lattice's interstitial locations. Two interstitial water molecules in barium chloride dihydrate.
