1
Q
What is the water in a lattice called?
A
The water of crystallisation.
2
Q
A hydrated solid contains what?
A
Water of crystallisation
3
Q
How is a salt anhydrous?
A
If it doesn’t contain water of crystallisation.
4
Q
How do you find the formula of hydrated salts?
A
Find the mass of the water lost by taking the mass of the anyhdrous salt away from the mass of the hydrated salt.
Find the number of moles of water lost.
Find the number of moles of anhydrous salt produced.
Work out the ratio of these moles (divide both by smallest number).
5
Q
