Curated OER
Fatty Acids For Soap Making
High schoolers titrate a sample of fatty acids with standardized sodium hydroxide solution. From the amount of base needed for neutralization and the mass of sample used for titration, the apparent average molar mass of the sample is...
Curated OER
Acids, Bases, and Buffers
In this acids and bases worksheet, students test the pH of different solutions to determine if it is basic or acidic. Students complete 7 short answer questions based on their results.
