A) Coordinated water                                     (p)open square brackets Cu open parentheses straight H subscript 2 straight O close parentheses subscript 4 close square brackets to the power of 4 plus end exponent SO subscript 4 superscript 2 minus end superscript times straight H subscript 2 straight O
B) Interstitial water                                         (q)straight C subscript 17 straight H subscript 35 COONa
C) Hydrogen-bonded water                            (r)BaCl subscript 2 times 2 straight H subscript 2 straight O
(s)open square brackets Cr open parentheses straight H subscript 2 straight O close parentheses subscript 6 close square brackets to the power of 3 plus end exponent 3 Cl to the power of minus

  1. A – (r), B – (s), C – (q) 
  2. A – (q), B – (r), C – (s) 
  3. A – (r), B – (q), C – (p) 
  4. A – (s), B – (r), C – (p)
