The expected osmotic pressure of the given solution of Fe 2 ( SO ) 4 and the value of K a for the dissociation reaction of Fe ( H 2 O ) 6 3 + is to be calculated. Concept introduction: Osmotic pressure is the amount of pressure required to be applied across a semi-permeable membrane in order to stop the flow of solvent molecules in a solution of lower concentration to higher concentration. Osmotic pressure is a colligative property. The value of osmotic pressure is calculated by the formula. π = i × C × R × T To determine: The expected osmotic pressure of the given solution of Fe 2 ( SO ) 4

(6 pts - 2 pts each part) Although we focused our discussion on hydrogen light emission, all
elements have distinctive emission spectra. Sodium (Na) is famous for its spectrum being
dominated by two yellow emission lines at 589.0 and 589.6 nm, respectively. These lines result
from electrons relaxing to the 3s subshell.
a. What is the photon energy (in J) for one of these emission lines? Show your work.
b. To what electronic transition in hydrogen is this photon energy closest to? Justify your
answer-you shouldn't need to do numerical calculations.
c. Consider the 3s subshell energy for Na - use 0 eV as the reference point for n=∞. What
is the energy of the subshell that the electron relaxes from? Choose the same emission
line that you did for part (a) and show your work.
