Journal Entry:

What types of Spectroscopy have we learn about already this year?    

Learning Intentions

• We will learn what Spectroscopy is, what the difference types are and how they are measures. 

• We will learn what absorbance and transmittance is and what scientific equipment you can use to measure these to determine concentration of an unknown.

• We will learn how to create a calibration curve using a number of dilution of a stock solution, determining the transmittance for each dilution and graphing the data to find a relationship between the two.

• We will learn how to interpret the results of an experiment regarding the absorption and transmittance of light to determine the concentration of an absorbing species in a solution.

Closing Task:

You can explain the relationship between a region of the electromagnetic spectrum and the types of molecular or electronic transitions associated with that region. 

You can explain how the amount of light absorbed by a solution of molecules or ions relates to the concentration, path length and molar absorptivity.
