Part 1 description: Using the salts provided in the VL cabinet determine the heat of solution of
MgSO4, K2SO4,
KNO3 and
NH4NO3.
To create a calorimeter in the virtual lab, right click on any piece of glassware
and choose "Thermal Properties.." In the Thermal Properties dialogue box, check "insulate".
Assume that the calorimeter container does not absorb any heat and that the
specific heat for the solution is 4.184 J/gºK (same as for water). The Virtual Lab is set up to enable you to
determine the literature values for the heats of solution which are required in the wet lab.
To ensure that the amount of solid added to the calorimeter is accurately recorded,
the mass of salt should be weighed out by differences. Click on "Solid" button
on the "Solution Information" window on the right. Highlight the jar of salt to
see the mass of the solid. Transfer the required amount to the calorimeter and check the
mass of the salt again.
