1. Using the second-derivative values for the point before and the point after the equivalence point, determine the equation of the line that passes through the equivalence point. Show your work in your notebook. 2. Using the equation of the line you determined, calculate the exact volume of added titrant at the equivalence point. Show your work in your notebook. 3. Determine the concentration of ferrous ammonium sulfate in solution. Show your calculation in your lab notebook.

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.
