Answer #1

Solution.

The scheme of the cell is S.C.E.|| titrated solution | Ag(s)

Therefore, the cell voltage is

After 10 mL of the titrant is added, the concentration of silver ions is

It means that we reached the equivalence point.

The cell voltage at the equivalence point will be determined by a solubility of AgBr.

The cell voltage is

Finding the Spring Constant We can describe an oscillating mass in terms of its position, velocity, and acceleration as a function of time. We can also describe the system from an energy perspective. In this experiment, you will measure the position and velocity as a function of time for an oscillating mass and spring system, and from those data, plot the kinetic and potential energies of the system. Energy is present in three forms for the mass and spring system....
