CHM211H5 Lecture 5: Unit 5 Chromatography
Document Summary
We talked about how to develop the method for that data. Looked at how we will select a sample. How to develop quantitative analysis (make calibration curves) Had a general idea to detect/ analyse sample. Quantitative (how much is it) and qualitative (what is it) analysis. Started to look at the different types of reactions that we can explore in terms of being able to dissolve an acid and measure something. They have to be distinguished, there are different types of rxns and they are used for different types of purposes. Complexometric rxns and titrations (metals which induces a change in colour) Detection of metals (metal indicators or also known as ligands. They are called metal indicators because they bind to a metal, 2a phenol-orange) Two organic compounds cannot bind to each other. When there is the binding of the metal there is a colour change which is considered the indication. Precscence of halides (silver nitrate) or the silver.
