Product Details

Hydrogen gas is prepared and tested more safely using microscale techniques. Hydrochloric acid reacts with zinc metal to produce hydrogen gas. The hydrogen gas is collected by water displacement in the bulb of a Beral-type pipet. Pure hydrogen gas as well as hydrogen mixed with air can be safely tested for flammability. Many trials can be run during one class period. All chemicals and specialized equipment are provided.

Complete for 30 students working in pairs.

Performance Expectations

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.
MS-PS1-4. Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.
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.
