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?

Kinetics Experiment Rate Law + Activation Energy
 
14:12
The rate law for 6I- + BrO3- + 6H+ --- 3H2O + Br- + 3I2 is determined using a clock reaction where the I2 reacts with thiosulfate until the thiosulfate runs out. Starch indicator is used to produce a blue color indicating that the iodine has reacted with all of the thiosulfate. The rate law is determined by mixing 10 mL of distilled water, 10 mL of 0.040 M KBrO3, 10 mL of 0.10 M HCl, 10 mL of 0.010 M KI and 10 mL of 0.0010 M Na2S2O3. In experiments 2-4, the amount of KI, KBrO3 and HCl are doubled and the distilled water is not added. This causes each to double in concentration for that experiment while all other concentrations remain constant. Finally the experiment is run with the same amounts as experiment #1, but at two different temperatures. This is used to measure the rate constants at these two temperatures in order to determine the activation energy for the reaction.

Beer Lambert's Law, Absorbance & Transmittance - Spectrophotometry, Basic Introduction - Chemistry
 
18:13
This chemistry video tutorial provides a basic introduction into spectrophotometry and beer lambert's law also known as beer's law. It briefly explains how a spectrophotometer works. It uses a light source and a monochromator which selects a specific wavelength of light using a prism or a grating. The amount of light striking the sample is the incident light Io and the intensity of light picked up by the detector is I. The ratio of I to Io is known as the transmittance. The absorbance is the negative log of the transmittance. As the transmittance increases, the absorbance decreases. Beer's Lambert law is associated with the equation A = elc where A is the absorbance, e is the molar absorptivity, l is the pathlength in cm and c is the concentration in Molarity or moles per liter. This video contains plenty of examples and practice problems calculating the absorbance, molar absorptivity and unknown concentration using beer lambert's law. This video explains how to determine the linear equation in slope intercept form given a data table of absorbance and concentration. It also explains how to determine the unknown concentration using proportions.

Calculating Equilibrium Concentrations-1
 
11:21
Given the equilibrium constant, Kc, and the initial concentrations, calculate the equilibrium concentrations of the reactants and products. This problem introduces the concept of solving for equilibrium concentrations/pressures using an "ICE" table and is a method used by many people to solve equilibrium problems.

Acid-Base Reactions in Solution: Crash Course Chemistry #8
 
11:17
Last week, Hank talked about how stuff mixes together in solutions. Today, and for the next few weeks, he will talk about the actual reactions happening in those solutions - atoms reorganizing themselves to create whole new substances in the processes that make our world the one we know and love. This week, we focus on acids and bases and their proton-exchanging ways.

Precipitation Reactions: Crash Course Chemistry #9
 
11:31
A lot of ionic compounds dissolve in water, dissociating into individual ions. But when two ions find each other that form an insoluble compound, they suddenly fall out of solution in what's called a precipitation reaction. In this episode of Crash Course Chemistry, we learn about precipitation, precipitates, anions, cations, and how to describe and discuss ionic reactions.
