The main topics in this section are exponent laws, polynomials, distributive property, and solving first degree equations. Please watch part 2 and 3 for a review of linear relations and geometry. If you watch all 3 parts, you will have reviewed all of grade 9 math in 60 minutes. Enjoy! Visit jensenmath.ca for more videos and course materials.
Buffer Solutions
By The Organic Chemistry Tutor
This chemistry video tutorial explains how to calculate the pH of a buffer solution using the henderson hasselbalch equation. It explains the concept, components, and function of a buffer solution. A buffer solution consist of a weak acid and its conjugate weak base counterpart. It's purpose is to maintain a relatively constant pH value. This video discusses the relationship between the pH and pKa values with the relative amounts of weak acid and weak base components in the buffer solution. This video contains plenty of examples and practice problems.
Optical Activity - Specific Rotation & Enantiomeric Excess - Stereochemistry Youtube
By The Organic Chemistry Tutor
This organic chemistry video tutorial explains how to calculate the specific rotation of an enantiomer given the observed rotation, the pathlength, and the concentration of the solution. It discusses how to determine if a molecule will show optical activity based on its chirality. It also provides the formulas needed to calculate the optical purity and enantiomeric excess. Those formulas can be used to calculate the relative percentages of the R and S isomers.
