Product Details

One-way glass stopcocks conveniently located on the top of this high-quality apparatus allow for easy collection of gases during electrolysis experiments. The large center reservoir bulb will easily handle the liquid displacement from the two side columns and prevent any overflow during your experiments. Electrodes and directions included. Requires ring stand, support clamp and a 9-V battery or DC power supply. Measures 41 x 17 cm.

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.
