Question

Why does the amount of O2 gas produced eventually plateau as you continue to add more H2O2?

Answer 1

Ans:- When hydrogen peroxide (H2O2, sold to the public as a 3% (m/m) solution in water as adisinfectant for cuts) is mixed with bleach (active ingredient is sodium hypochlorite,NaOCl, sold to the public as a 6% (m/m) solution in water), oxygen gas (O2) is one ofthe products.In this experiment, you will measure the volume of oxygen gas producedwhen known amounts of hydrogen peroxide are mixed with known amounts of bleach.Based on the moles ofreactantsused (bleach and hydrogen peroxide) and the volumeof oxygen gas produced (product), you will determine thestoichiometry(mole ratio) ofthe reactants of the chemical reaction.
