Mini Lab Microscale

In our chemistry mini-lab today, we were basically mixing different chemicals together on a chart and recording their reactions. Some concluded with no observable reaction whereas others turned colors and some even produced precipitants. An example of a precipitant producing mixture was the NaOH and the AgNO. As we mixed these droplets together we noticed a brown clumping in the center of the droplets. As we blew it with air they formed more dense clumps and turned into a solid structure. Our next task on our list was to figure out the chemical name to each compound that we mixed. At first this was easy because it was cations first and then anions. The formulas began to become more complex as subscripts were added which tells you how many of each element there are. To have a correct formula the two ions must be equal which will make the entire thing equal. So if you are given Ag+ and Cl-, the formula would be AgCl because you have both a positive and a negative. The ions are denoted by the subscript tells how many of each element is needed for each other particular compound. In a formula the cation comes first and then the anion because that is a rule of the nomenclature. Patterns in nomenclature deal with the oxyanions. Due to the specific numbers of the element the suffixes will be different.
