Product Details

One-way glass stopcocks located at the top of the apparatus allow for simple and controlled collection of gases during electrolysis experiments. The large center reservoir bulb accommodates liquid displacement from the two side columns and prevents overflow while running. The included electrodes feature a 3.3 mm × 5.2 mm platinum foil attached to a copper wire lead and sealed in an outer plastic tube, each fitted with a #1 rubber stopper. A ring stand, support clamp, and 9-V battery or DC power supply are required for operation. WARNING: This product can expose you to chemicals including benzene and lead, which are known to the State of California to cause cancer, birth defects, or other reproductive harm.

Performance Expectations

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.
HS-PS1-5. Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.
HS-PS3-5. Develop and use a model of two objects interacting through electric or magnetic fields to illustrate the forces between objects and the changes in energy of the objects due to the interaction.
