Compound Light Microscope The familiar compound light microscope is a series of lenses (hence "compound") that focus visible light in such a way as to produce a magnified image. A single lens‚ often called a magnifying glass‚ cannot generally magnify images as much as a series of lenses although Antony van Leeuwenhoek‚ the first microbiologist‚ used a simple‚ albeit exquisitely crafted‚ lens to discover single-celled "animalcules‚" as he called them. Advantages: Basic compound light microscopes

Investigation: 20 How much cobalt is in the soil? Introduction: By completion of investigation 20‚ a standard curve of absorbance versus known cobalt (II) nitrate was prepared. The concentration of cobalt (II) ion obtained from a soil sample was determined. Whether or not cobalt nitrate should be added to the soil was determined. If cobalt nitrate needs to be added‚ then how much will it be required to meet the necessary nutritional needs of the animals was established. In colorimetry

properties of an unknown ionic compound. In order to do this successfully the group has to use a variety of methods and run several tests on the unknown compound. By doing this the group will be able to identify the different chemical and physical properties of the compound that will help obtain the identity of the specific compound given. The group will devise two syntheses of the compound‚ and compare them for cost effectiveness‚ safety and potential yield of the compound. So to be more specific about
