Identifying Ionic Compounds Written by Ashleigh Lara. In our experiment we were given 5 different cations who’s mixture of anions ranged from five to three different solutions. At every single station we were given the following materials a spot plate‚ a dropper‚ and the chemicals used to mix with our main substance. Each substance received 3 drops of the different chemicals which were able to give us an observation of what the compound was made into. Many of our experiments color‚ texture and solubility

Four elements‚ hydrogen‚ carbon‚ oxygen and nitrogen‚ are the major components of most organic compounds. Consequently‚ our understanding of organic chemistry must have‚ as a foundation‚ an appreciation of the electronic structure and properties of these elements. The truncated periodic table shown above provides the orbital electronic structure for the first eighteen elements (hydrogen through argon). According to the Aufbau principle‚ the electrons of an atom occupy quantum levels or orbitals starting

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
