Set up a complete electrolysis demonstration within minutes! This rugged, economical electrolysis apparatus is easy to operate and perfect for student use-simply fill the tubes with an electrolyte solution, place them in a battery jar or 600-mL beaker, mount the tubes, insert the electrodes, and it's ready to go! Comes with stainless steel electrode pair, nonconducting support base, two test tubes, two rubber stoppers, and detailed instructions for use. Operates on a 9-V battery or DC power supply, not provided. Available with or without battery jar.
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-PS1-4: Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.
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-PS2-6: Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.
