The Chemistry of Chromium (Demo)

Violet solution of Cr(H 2 O) 6 3+. C: The color of the solution changes from violet to an acid green. D: Green Cr(OH) 3 precipitates from the green solution. More base will cause the solid to redissolve to give a green chromite Cr(OH) 4-solution. E: The green solution changes to orange as the CrO 4 2-/Cr 2 O 7 2-ions are formed. E + HCl

Department of Chemistry Introduction to Circular Dichroism

An introduction to circular dichroism spectroscopy Circular dichroism (CD) is the difference in the absorption of left‐handed circularly polarised light (L‐CPL) and right‐handed circularly polarised light (R‐CPL) and occurs when a molecule contains one or more chiral chromophores (light‐absorbing groups).

Fog Chamber: ChemistryFluids Science Activity

Clouds form when invisible water vapor in the air cools enough to form tiny droplets of liquid water. In the atmosphere, this usually happens when moist air rises to higher altitudes. At higher altitudes, the pressure is lower, so the gas expands, loses internal energy, and cools. You can create the same effect by rapidly expanding the air in a jar.

Burning Phosphorus . Phosphorus is found in three main forms: white, red, and black. (There are also numerous allotropes of each of these forms.) White phosphorus is a soft, waxy, flammable substance, consisting of tetrahedral P 4 molecules; it is often slightly yellowish because of the presence of impurities (hence, it is sometimes imaginatively known as yellow phosphorus).

Smoke Visibility and Obscuration

In a fire calculation using the simple chemistry approach, the smoke is tracked along with all other major products of combustion (McGrattan et al. 2021). This means that for every cell in the model, the smoke density is known. The light extinction coefficient, (K), is the key parameter used to calculate both visibility and light obscuration.
