Performance Assessment

In this lab experience, students carry out an investigation to determine how reaction rate changes based on reactant concentration and temperature. Students should come to understand that as the concentration of hydrogen peroxide is decreased, the reaction rate decreases. Also, when the temperature of the sodium acetate solution increases, the rate of dissolution increases.

Product Details

Safety: Hydrogen peroxide solution, 30%, is severely corrosive to the skin, eyes, and respiratory tract: it is a very strong oxidant. Dangerous fire and explosion risk. Do not heat this substance. Sodium iodide is slightly toxic by ingestion. Although the Alconox detergent is considered nonhazardous, do not ingest the material. Do not stand over the reaction; steam and oxygen are produced quickly. Wear chemical splash goggles, chemical-resistant gloves, and a chemical-resistant apron. Please review current Safety Data Sheets for additional safety, handling, and disposal information.
