College Chemistry Tutorials
United States
เข้าร่วมเมื่อ 18 ธ.ค. 2020
This channel is for 1st and 2nd year college chemistry students. High school chemistry students will also find this channel helpful. I hope all educators, K-12 and higher education, will find these videos useful. I have taught general and organic chemistry, and chemistry for engineers since finishing graduate school in 2011. I'll be adding short tutorials that my students have found very helpful. I hope you will find these videos helpful as well. Thank you for visiting.
Determining the Formula of a Hydrate Lab
The Chemistry Laboratory Series: Determining the Formula of a Hydrate
In this lecture we’ll look at determining the formula of copper(II) hydrate. First, I’ll explain the concepts of what data needs to be collected and how we can use the data to find the hydrate formula. Next, I show each step of the lab. Finally, I'll use the data I collected to show you how to find the formula of copper(II) hydrate. For my students, this is a required video of our pre-lab assignment.

Reaction Quotient Tutorial
มุมมอง 13หลายเดือนก่อน
In this lecture, I'll explain the reaction quotient and what it means. I'll provide three example tutorials. Video Thumbnail: Finding the reaction quotient helps us determine if the system is at equilibrium. If the system is not at equilibrium then the system will shift, much like the flag on this beach, to reach equilibrium. Video Thumbnail Photo Credit: MS365 Powerpoint #equilibrium #equilibr...
Creating a Calibration Curve with Equation in Excel Tutorial
มุมมอง 88หลายเดือนก่อน
In this video, I'll explain how to create a calibration curve from density lab data of various mass percent concentrations of NaCl solutions. I'll also show how to display the equation of the trendline so that we can use it to find the mass percent concentration of an unknown NaCl solution based on the density found in lab. #chemistry #chemlab #densityofsolutions #msexcel #exceltutorial #naclso...
Chemical Equilibrium: The Equilibrium Constant
มุมมอง 27หลายเดือนก่อน
In this lecture, I'll explain the the equilibrium constant and what it means. I'll provide some examples with an explanation. Video Thumbnail: Equilibrium represents a fine balance of reactants and products in a reaction, much like the balance of these stones on a beach.

Chemical Equilibrium: An Introduction
มุมมอง 222 หลายเดือนก่อน
In this lecture, I'll explain the basics of chemical equilibrium: when the concentrations of the reactants and products DO NOT change with respect to time. I'll also include a brief thermodynamic definition of equilibrium with respect to the change in Free energy which is usually introduced in the second semester of general chemistry. Video Thumbnail: Equilibrium is usually symbolized by the "d...
Mole Fraction and Molarity And Molarity of Nitric Acid
มุมมอง 102 หลายเดือนก่อน
Here, I will show you how to find the molarity, molality, and mole fractions of a 60.% by mass nitric acid in water solution. Video Thumbnail: nitric acid is a used to react with precursors in many organic synthesis reactions including synthesizing nylon like the nylon ropes shown in the image.
