Lecture Room Temperature Meter

Procedure

• On a stir motor.

• Measure the temperature with the temperature probe.

• Add 40gm LiCl. Temperatures rises about 60 degrees Celcius.

  Caution. Beaker gets hot enough to cause burns.

Reactions

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

dH = -37.1 kJ/mole = -875 J/gm
