Learn about galvanic (voltaic) and electrolytic cells. You'll also get information about anodes and cathodes and direction of electron flow in the two electrochemical cells.
Balancing Redox Reactions
Get step-by-step instructions for balancing redox reactions for conservation of mass and charge in electrochemistry.
The Nernst equation is used to calculate the voltage of an electrochemical cell or to find the concentration of one of the components of the cell. Here is a look at the Nernst equation and an example of how to apply it to solve a problem.
Electroplating is the application of electrolytic cells in which a thin layer of metal is deposited onto an electrically conductive surface. Here's a closer look at what electrochemistry is, how it works, and what metals and anodes are used.
Experimental Determination of Avogadro's Number
Did you know that Avogadro's number isn't a mathematically derived unit. The number of particles in a mole of a material is determined experimentally. This easy method uses electrochemistry to make the determination.
Battery - Diagram of Daniell Galvanic Cell
Here's a handy gif to help you illustrate the working of a galvanic cell.
Bend Water with Static Electricity
Use static electricity to bend a stream of flowing water. This is an easy science activity that illustrates how opposite electrical charges attract each other.
Chemistry Fun with Pennies
Use pennies, nails, and a few simple household ingredients to explore some of the interesting properties of metals. Clean the pennies chemically, make verdigris, and plate the nails with copper.
