Heat of Solution of Lithium Chloride

Procedure

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

Reactions

LiCl (s) + H₂O (l) --> Li⁺ (aq) + Cl^- (aq)

dH_soln = -37 kJ/mole = -875 J/gm
