Properties of hydrogen chloride (Practical Chemistry) This is a particularly good experiment for demonstrating the solubility of hydrogen chloride, but the fountain demonstration should be practiced first and always carried out in a fume cupboard. THINKING CONCEPTUALLY Astronomy: Spectroscopy (YouTube) This series of three YouTube videos puts atomic line spectra in the context of astronomy. The first two videos are the most relevant with the first going over basic ideas involving electronic energy levels, and the second taking those ideas forward explaining how they provide information on stars. THINKING CONTEXTUALLY Light energy and photochemical reactions (Steve Spangler Science) This simple practical (follow the Try ‘Now This!’ section) uses photosensitive paper to show the link between the wavelength or frequency of light and the energy it carries.
