Saturated solution |
Maximum solute dissolved in the solvent |
|
|
Unsaturated solution |
Less than than the maximum solute dissolved. (More added solute can dissolve) |
|
|
Super-Saturated solution |
More than maximum solute dissolved. Unstable solution, usually a precipitate. |
|
|
Enthalpy of Solution |
ΔHsoln |
|
|
ΔHsoln = |
ΔHsolute + ΔHsolvent + ΔHmix |
|
|
ΔHsolute = |
Endothermic |
|
|
ΔHsolvent = |
Endothermic |
|
|
ΔHmix = |
Exothermic |
|
|
ΔHsolute + ΔHsolvent = ΔHmix |
ΔHsoln = 0 |
|
|
ΔHsolute + ΔHsolvent < ΔHmix |
ΔHsoln < 0 (negative) |
|
|
ΔHsolute + ΔHsolvent > ΔHmix |
ΔHsoln > 0 (positive) |
|
|
Heat of hydration = |
ΔHhydration |
|
|
Heat of hydration |
Enthalpy(H) change when 1mol of a gaseous solute ions dissolves in water |
|
|
ΔHsoln = For hydration |
ΔHsolute + ΔHhydration |
|
|
ΔHhydration = (endo/exo) |
Exothermic |
