Question

Define Water of Crystallisation along with the suitable example. [2]
ii) Calculate the relative atomic mass of Chlorine, which consists of 75% of 35Cl17 and 25% of 37Cl17 . [​

Answer 1

Water of crystallization is defined as water that comes from a crystal substance after heat is applied. An example of water of crystallization is the water that drips off of a water crystal hanging from the eaves of the house as it warms up after a freezing rain.

Average atomic mass = ? = 35.50 amu. Conclusion: The average atomic mass of chlorine if it exists commonly in two isotopes 35/17 Cl (75%) and37/17 cl(25%) is 35.50amu.

Answer 2

Classically, "water of crystallization" refers to water that is found in the crystalline framework of a metal complex or a salt, which is not directly bonded to the metal cation. Upon crystallization from water or moist solvents, many compounds incorporate water molecules in their crystalline frameworks.
