Product Details

General, Organic and Biological Chemistry Healthy body, good teeth, strong bones—the benefits of calcium in good nutrition are well known. Milk and dairy products are widely promoted as an important source of calcium in the diet. Explore the chemistry behind the nutrition with this experiment that measures the amount of calcium in milk. Students analyze the calcium content in skim milk by microscale titration with EDTA. An excellent activity to “bone-up” on calcium properties and titration skills! Complete for 24 students working in pairs.

Performance Expectations

MS-PS1-1. Develop models to describe the atomic composition of simple molecules and extended structures.
MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
