Enthalpy Of Soloution Flashcards
1
Q
What is Enthalpy of soloution
A
The enthalpy change when 1mole of an ionic substance is dissolved in the minimum amount of solvent to ensure no further Enthalpy change is observed upon further dilution
2
Q
For a substance to dissolve
A
-substance bonds must break (endothermic)
- new bonds must be formed between the solvent and substance (exothermic)
3
Q
Solution chain
A
Ion lattice in solid form.
Substance bonds broken to create free moving ions.
Bonds formed between ions and water. The ions are hydrated.
4
Q
The water molecules
A
Surrounded the ions in a process called hydration
5
Q
What needs to happen for hydration to happen
A
