Lab Experiment #13: The Equilibrium Constant.
 
08:17
This video is about the AP Chemistry Lab Experiment #13: A Spectrometric Determination of Keq of the Iron(III)-Thiocyanate System. In this video you will learn how to determine the equilibrium constant of a system using Beer-Lambert law. In the video, a spectrophotometer is used to measure the absorbance of the Iron(III)-Thiocyanate solution in order to find the equilibrium concentrations of the system components and the determine Keq. Students studying Chemistry at different levels could highly benefit from this video. You can refer to the link below to watch a detailed video that explains the Beer-Lambert and its uses.

The Determination of Keq for FeSCN2+  AP Chemistry
 
03:41
Colorimetric or Spectrophotometric Analysis In this two-part lab, students will determine the equilibrium constant for the reaction of iron(III) ions with thiocyanate ions (SCN-). In Part 1, a series of reference solutions containing the product ion, iron(III) thiocyanate (FeSCN2+), is prepared. Students then make up test solutions containing a fixed amount of iron(III) ions and different amounts of the SCN- ion. These solutions are analyzed in Part 2 using a colorimeter. The first set of solutions is used to generate a calibration curve of absorbance versus the concentration of FeSCN2+ ions. The second set of solutions is then analyzed and the FeSCN2+ ion concentration of each solution is determined. The students use the data to calculate the equilibrium constant for the reaction of iron(III) ions with thiocyanate ions (SCN-). Students gain valuable experience in the techniques of quantitative transfer, along with the process of colorimetric determination.

The Equilibrium Constant
 
06:15
065 - The Equilibrium Constant In this video Paul Andersen defines the equilibrium constant (K) and explains how it can be calculated in various reversible reactions. The equilibrium constant is a ratio of the concentration of the products to the concentration of the reactants. If the K value is less than one the reaction will move to the left and if the K value is greater than one the reaction will move to the right. Do you speak another language?

What is Ksp? (Solubility Product Constant)

Ksp is really just an equilibrium constant (Keq), but it's for a solid dissolving in water. This is special, since all of the reactants are solid, and so they AREN'T included in the equilibrium expression.
