Students investigate the need for measuring concentrations in normality in titrations. In this titrations and normality lesson plan, students perform titrations and use different indicators to show they change colors at different pH values. They also perform 3 titrations using different molarities of acids and the some molarity of base. They determine that molarity is not sufficient for some titrations and that normality is necessary.
Sal continues his explanation of The Ideal Gas Equation in this chemistry video. He sets up a different problem from the previous video, and uses the ideal gas equation to calculate the molar mass of a 98 ml container that contains .081 grams of a substance at standard pressure and temperature.
Wow! This comprehensive collection of slides will walk your chemistry class through the foundation of chemical reactions, teach them to balance equations, differentiate types of reactions, and calculate stoichiometry problems. This will save you time in creating individual informative slides, but you might want to rearrange them in a way that is more coherent. Also, you probably would not want to teach all of this material in one day! Please also note that hyperlinks to worksheets do not work.
A 30-question multiple choice chemistry test challenges takers. Topics touched upon include thermochemistry, equilibrium, behavior of gases, and pH. Problem solving is required in order to answer most of the questions. Other questions require critical thinking skills and reading phase diagrams. Content is solid, but there are unusual subheadings for each section that may make it undesirable for your use.
The previous video illustrated what happened when a strong acid is added to water. This presentation illustrates what happens when a weak acid is added. On the left axis, pH levels are measured. The horizontal axis represents two liters of water. The weaker acid is added to the water. This video shows what happens to the pH levels, and how the equivalence point is determined based on how much of the weak acid is added.
Learners investigate electrochemistry. In this chemical reactions and electricity lesson, students test solution for conductivity using a conductivity apparatus. They perform a redox reaction and measure the voltage of the solutions and connect the solutions using a U-tube. They also perform an electroplating experiment to see how a chemical reaction will occur from the electric current.
A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there are many problem solving opportunities.
