Breaking Down H2O: Exploring Molecular Processes Through Electrolysis
Help me give my students a reliable 12V DC power supply and alligator clip cables to see a hands-on electrical circuit experiments involving a Hoffman apparatus and explore fundamental concepts in stoichiometry.

My Project
My chemistry students are fascinated by the invisible world of atoms and molecules, but abstract chemical equations can be challenging to grasp. They're eager to see the mathematical precision of chemistry come to life through real experiments.
The 12V DC power supply is essential for running our Hoffman apparatus, which will demonstrate water electrolysis - the decomposition of water into hydrogen and oxygen gases.
This professional-grade equipment will provide the consistent electrical current needed to:
Split water molecules (H2O) into their component elements
Generate measurable volumes of hydrogen and oxygen gases
Maintain steady electrolysis for accurate data collection
The alligator clip cables will securely connect our power supply to the Hoffman apparatus electrodes, ensuring:
Safe and reliable electrical connections
Easy setup and breakdown for multiple class periods
Proper current flow to both electrodes
Together, these resources will transform the abstract concept of stoichiometry into a visible, measurable phenomenon. My students will:
Observe the 2:1 mole ratio of hydrogen to oxygen firsthand
Collect and measure gas volumes to verify chemical equations
Calculate molar relationships using real experimental data
Connect mathematical ratios to actual chemical reactions
This hands-on experience will cement their understanding of fundamental chemistry concepts like balanced equations, mole ratios, and the law of definite proportions. When students see exactly twice as much hydrogen as oxygen bubbling up in the collection tubes, the elegance of chemistry's mathematical relationships becomes unforgettable!
More than half of students from low‑income households
