Interpretation: This is to be proved that the energy levels of hydrogen atom are not continuous but quantized.
Concept introduction: According to

Answer to Problem 65A
The energy levels of hydrogen atoms are quantized.
Explanation of Solution
By observing the line spectrum of hydrogen,one can prove this fact.
When electricity is passed through a gas, light is emitted. When this light is passed through a prism only certain lines of light in the image is observed. This is called line spectra.
When a glass tube is filled with H2 gas at low pressure and
The hydrogen atomabsorbs or emits radiation of a certain frequenciesthus, these atoms can only absorb or emits radiation with certain energies. This is the reason of getting discrete colored lines corresponding to specific wavelength of transition of electrons from two different energy levels.
The energy levels of hydrogen atoms are quantized.

- For each scenario below, select the color of the solution using the indicator thymol blue during the titration. When you first add indicator to your Na2CO3solution, the solution is basic (pH ~10), and the color is ["", "", "", "", ""] . At the equivalence point for the titration, the moles of added HCl are equal to the moles of Na2CO3. One drop (or less!) past this is called the endpoint. The added HCl begins to titrate the thymol blue indicator itself. At the endpoint, the indicator color is ["", "", "", "", ""] . When you weren't paying attention and added too much HCl (~12 mL extra), the color is ["", "", "", "", ""] .
