Hello everyone! In this time of class on-line , one of the best subject is analytical chemistry. This subject it is about analysis of a sample doing different tests it is possible to find out element of the periodic table makes up the sample, for example , Flame test.In this test, placing the sample on fire will show a colour, this colour can be, for example, orange or green and will be calcium or barium.There are more tests to be able to be more accurate with the type of sample. I like the idea of being able to determine a substance in the lab, in adittion, it's my first time that can be felt beyond a theorical subject. Before I studied this subject,I thought I would be a subject boring because in the planning included a lot of content from an earlier subject called "General chemistry II",besides, in this subject there were many problems with teachers on evaluation issues, but I am surprice with Analytical chemist...
