Interpretation: To describe what might happen when two different liquids are mixed, the volume of the mixture is larger than the sum of the volumes of the two components.
Concept Introduction: A non-ideal solution deviates from the ideal solution's norms, in which the interactions between particles are the same (or extremely similar) to those between molecules of different components.
Explanation of Solution
In ethyl alcohol, hydrogen bonding is present which is a strong intermolecular bond. When ethyl alcohol is added to water, the newly formed hydrogen bond between ethyl alcohol and water is weaker than the present between ethyl alcohol. When interactions are weak, the volume expands.
Thus the volume of the mixture of ethyl alcohol and water is more than the sum of individual volumes.

Below is just the information I used to get the graphs obtain the graph please help. Prepare two graphs, the first with the percent transmission on the vertical axis and concentration on the horizontal axis and the second with absorption on the vertical axis and concentration on the horizontal axis. Solution # Unknown Concentration (mol/L) Transmittance Absorption 9.88x101 635 0.17 1.98x101 47% 0.33 2.95x101 31% 0.51 3.95x10 21% 0.68 4.94x10 14% 24% 0.85 0.62 A.) Give an equation that relates either the % transmission or the absorption to the concentration. Explain how you arrived at your equation. B.) What is the relationship between the percent transmission and the absorption? C.) Determine the concentration of the ironlll) salicylate in the unknown directly from the graph and from the best fit trend-line (least squares analysis) of the graph that yielded a straight…arrow_forwardDon't used Ai solutionarrow_forward
- Calculate the differences between energy levels in J, Einstein's coefficients of estimated absorption and spontaneous emission and life time media for typical electronic transmissions (vnm = 1015 s-1) and vibrations (vnm = 1013 s-1) .
