Heat of Solution of Lithium Chloride


600 mL Beaker

Big Lecture Room Meter with Temperature Probe

Bottle of Lithium Chloride (premeasured at 60 grams)



  1. Add about 200ml water to a 600ml beaker. Add about 60gm LiCl. Temperature increases to about 60oC.
  2. Immerse the probe from the lecture size temperature meter to show class the temperature increase.


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).
