High schoolers investigate the need for measuring concentrations in normality in titrations. In this titrations and normality lesson, 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.
Background details and trivia about the chemical and physical properties of elements will be interesting for your class. This instructional activity asks for some explanations of processes, but also for some calculations about molarity and chemical formulas after reactions.
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.
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.
