Heat of Solution of Lithium Chloride
Materials
600 mL Beaker
Big Lecture Room Meter with Temperature Probe
Bottle of Lithium Chloride (premeasured at 60 grams)
Procedure
- Add about 200ml water to a 600ml beaker. Add about 60gm LiCl. Temperature increases to about 60oC.
- Immerse the probe from the lecture size temperature meter to show class the temperature increase.
Reactions
LiCl (s) + H2O (l) --> Li+ (aq) + Cl- (aq)
dHsoln = -37 kJ/mole = -875 J/gm
Waste Management
The Lithium chloride solution should be sent to EH&S as hazardous waste (Toxic).
