|
| Transition Metals (Movie/Animation, Audio/Visual (4)) |
| Various chlorides of transition metals mixed with methanol are sprayed into the flame of a Bunsen burner. |
|
| Flame Colors (Movie/Animation, Audio/Visual (4)) |
| Substances are introduced into a flame in various ways. The color of the resulting flame depends on the substance. These are organized by method/technique. |
|
| Sprayed into Burner Flame (Movie/Animation, Audio/Visual (4)) |
| Saturated methanol solutions of approximately 1.0 M were sprayed into the flame of a Bunsen burner. The spray produces characteristic atomic emission colors. |
|

| Spectrometer, Spectronic 20 (ChemPages Lab) (Instructional Material (1)) |
| Spectrometer, Spectronic 20?: this is a resource in the collection "ChemPages Laboratory Resources". The Spectronic 20? is used to measure the absorbance (or transmittance) of solutions. A Spectronic 20? is capable of measuring % transmittance and absorbance over the range of 340 to 950 nm (the range 600 to 950 nm requires a special infrared filter and a different lamp). The ChemPages Laboratory Resources are a set of web pages that include text, images, video, and self check questions. The topics included are those that are commonly encountered in the first-year chemistry laboratory. They have been put together for use as both a pre-laboratory preparation tool and an in-laboratory reference source. |
|
| Spectrophotometer, Scanning UV-Visible (ChemPages Lab) (Instructional Material (1)) |
| Spectrophotometer, Scanning UV/Visible: this is a resource in the collection "ChemPages Laboratory Resources". A scanning ultraviolet/visible (UV/Vis) spectrophotometer operates on the same principles as a Spectronic 20?. They both can be used for qualitative and quantitative analysis. The ChemPages Laboratory Resources are a set of web pages that include text, images, video, and self check questions. The topics included are those that are commonly encountered in the first-year chemistry laboratory. They have been put together for use as both a pre-laboratory preparation tool and an in-laboratory reference source. |
