Lab #14: Structure & Concentration in Acid and Base Titrations

Description

Students will conduct a series of acid–base titrations and determine the concentrations of two unknowns. They will create a procedure to collect quantitative titration data using a buret and pH meter. Using titration data that they collected, they will determine the concentration of each unknown. The activity contains enough materials for 15 groups of students as well as a Teacher’s Guide and Student Study Guide Copymasters.
