Chemical Reaction Lab
This lab workstation focuses on two key chemical reactions: neutralization and decomposition. The first experiment involves the reaction between sodium bicarbonate (baking soda) and acetic acid (vinegar), producing sodium acetate, water, and carbon dioxide. The reaction demonstrates acid-base neutralization. The second experiment explores the decomposition of hydrogen peroxide, where it breaks down into oxygen and water. Potassium iodide (KI) is used as a catalyst to facilitate the reaction.

Presentation Transcript
Workstation 5 • It is a neutralization (acid - base) reaction. Sodium Bicarbonate (baking soda) is a base, it reacts with the acetic acid (vinegar) to produce water (H2O) and Sodium Acetate. In the process it also evolves CO2 (carbon dioxide) as a product. • HC2H3O2 (acetic acid) + NaHCO3 (sodium bicarbonate) -> NaC2H3O2 (sodium acetate) + H2CO3 • The H2CO3 is not stable and breaks down quickly to form water and Carbon dioxide: (H2CO3 -> H2O + CO2).
Workstation 4 • The decomposition of hydrogen peroxide • hydrogen peroxide oxygen + water.H2O2(aq) O2(g) + H2O(l) • We used KI as a catalystthereforeitshouldbewrittenabove the arrow.
