In an experiment to determine the heat of precipitation of silver nitrate,
50 cm3 of 1.0 mol dm-3 hydrochloric acid is added to 50 cm3 of 1.0 mol dm-3 silver nitrate solution.
The following results are obtained.
Initial temperature of silver nitrate solution (oC)
Initial temperature of hydrochloric acid solution (oC)
Highest temperature of the mixture (oC)
Calculate the heat of precipitation of silver chloride, AgCl
[Specific heat capacity of water is 4.2 J g-1 oC-1 and density of water is 1 g cm-3]
