Concentration and Molarity - Student Laboratory Kit

By: The Flinn Staff


Students will use acid–base titrations to determine the concentration of unknown acid and base solutions in this laboratory activity. First, students will determine the concentration of an unknown hydrochloric acid solution by titrating with a THAM solution they prepare from their own calculations. Then, they will determine the concentration of an unknown sodium hydroxide solution by titrating with a known sulfuric acid solution. Calculations are involved for both titrations, so students will get practice with titration calculations involving both monoprotic and diprotic acids.

Six unknown solutions are included in the kit—three acid solutions and three base solutions. Kit also includes reproducible student handouts with detailed background section covering titration calculations and complete Teacher Notes with sample calculations and answers to questions, plus all chemicals needed to perform the lab.

Complete for 30 students working in pairs. Super Value Kit is complete for 5 classes of 30 students working in pairs. Fifteen reusable, 24-well reaction plates are required and available separately.
