Introduction This learning module introduces students to acid-base titrimetry at a level suitable for an introductory course in analytical chemistry. The module assumes students are comfortable with stoichiometric calculations, particularly as they […]
Students explore titrations of weak acids and based using a titration simulator.
Students explore various aspects of solubility when completing this activity.
Students will learn to:
Calculate the pH of a solution containing strong and/or weak acids and/or bases.
Assess the reasonableness of a calculated pH of an acid/base solution.
Students will learn to:
List and describe the factors/parameters that affect the shape of acid-base titration curves
Predict and explain why the change occurs when each of these factors/parameters is adjusted
Calculate the pH of solution and articulate its correlation to any point on the titration curve
Identify the different features on a diprotic acid titration curve
This module provides an introduction to Scanning Probe Microscopy (SPM). SPM is a family of microscopy techniques where a sharp probe (2-10 nm) is scanned across a surface and probe-sample interactions are monitored. SPM is […]
Basic electrochemical concepts including electrochemical cells are covered in this activity.
After completing the lab activity, students will be able to: Design an effective sampling strategy of solids by considering the necessary aspects of matrix and analyte (e.g. population vs. sample, phase of […]
