Mass of water driven off = 0.15 g
Moles of anhydrate 0.00257 moles
Moles of water driven off = 0.00833 moles
Moles of water per mole of hydrate = 3 moles
Molecular formula of the Hydrate is X.3H₂O where X is the anhydrate salt.
Cu(NO₃)₂ + 2 KI ---> 2 KNO₃ + CuI₂
The ideal mole ratio is 1 : 2
The limiting reactant will be KI.
What is the mass of water driven off?
A hydrate salt is salt that contains water of crystallization.
The mass of water driven off = 0.5 - 0.35 g
Mass of water driven off = 0.15 g
Moles of anhydrate = 0.35/136
Moles of anhydrate = 0.00257 moles
Moles of water driven off = 0.15/18
Moles of water driven off = 0.00833 moles
Moles of water per mole of hydrate = 0.00833/0.00257
Moles of water per mole of hydrate = 3 moles
Molecular formula of the Hydrate is X.3H₂O where X is the anhydrate salt.
The double replacement equation is given below:
Cu(NO₃)₂ + 2 KI ---> 2 KNO₃ + CuI₂
The ideal mole ratio for the reaction of Cu(NO₃)₂ and KI is 1 : 2
If 6 moles of Cu(NO₃)₂ was added to 2 moles of KI, the limiting reactant will be KI.
In conclusion, a hydrated salt is a salt that contains water of crystallization.
