Product Details

Classic AP Requirement #1—Determination of the Formula of a Compound

Students decompose silver oxide by heating a sample in a crucible. By using analytical techniques, the empirical formula of silver oxide is determined. The Law of Multiple Proportions and the Law of Conservation of Mass are demonstrated. Students gain valuable hands-on experience using an analytical balance and a crucible. An alternate procedure for the laboratory is included along with supplemental questions.

Complete for 24 students working in pairs.

Determination of the Empirical Formula of Silver Oxide Inquiry Guidance and AP® Chemistry Curriculum Alignment Transition Guide available! Follow the link in Resources to find this valuable publication that lets you adapt this classic AP Chemistry experiment for guided-inquiry and correlate with the AP Chemistry curriculum framework.


Materials Included in Kit: 
Silver oxide, 30 g

Additional Materials Required (for each lab group): 0.001-g precision balances (3 to share), crucibles and crucible lids, clay triangles, crucible tongs, wire gauzes with ceramic centers, Bunsen burners, watch glasses (optional), ring clamps, support stands. 

Note: The cost of silver oxide and other precious metals is currently volatile. Flinn Scientific continues to combat this constant price fluctuation by offering low prices that are guaranteed for a full year! Flinn Scientific has done and will continue to do everything we can to keep the costs affordable for our customers in order to mitigate the potential effect on teachers’ favorite lab activities and on chemistry education in general.

Performance Expectations

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-PS1-7. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
