Colorimeter- Definition, Principle, Parts, Uses, Examples
Principle of Colorimeter. When an incident light beam with intensity I 0 passes through a solution, a part of the incident light is reflected (I r) and absorbed (I a) while the remaining incident light is transmitted (I t).. i.e., I o = I r + I a + I t. The measurement of (I 0) in the colorimeter eliminates (I r), and it is sufficient to calculate the …

Classroom Resources | Extracting Copper From Ore | AACT
In this lab, you will extract copper from copper carbonate in two different ways, and then determine which industrial method is most effective. Method #1: Smelting. Smelting involves the use of a high-heat blast furnace and a reducing agent (like coke, which is a form of carbon) to extract the metal. In this case it is a two-stage reaction.
8.2.6 Colorimetry & Complex Ions
Colorimetry can be used to measure the absorption of radiation using a colorimeter. This uses a lamp as a source of white light, which passes through a filter to produce light of one colour. This colour will be the one that the sample will absorb the most and is called its complementary colour. For example hexaaquacopper (II) solution is a pale ...
