Final Answer:
During the decomposition of hydrogen peroxide, oxygen gas is trapped in the soap bubbles. Therefore the correct option is a.
Step-by-step explanation:
During the decomposition of hydrogen peroxide
into water
and oxygen
, the gas trapped in the soap is oxygen. This chemical reaction involves the breakdown of hydrogen peroxide molecules into water and oxygen gas. The formula for this reaction is
→
. As a result, the oxygen gas released during this reaction forms bubbles in the soap, trapping the gas and causing it to expand, creating foam or bubbles.
Hydrogen peroxide naturally decomposes over time, and when a catalyst, such as a detergent or soap, is introduced, it accelerates this decomposition. The oxygen gas produced is what creates the bubbles in the soap. This reaction is often used in various applications, including in the production of foam for cleaning products or in demonstrations to showcase the decomposition of hydrogen peroxide into water and oxygen gas.
Understanding this chemical reaction and its byproducts helps in comprehending the properties of hydrogen peroxide and its applications in different fields, including chemistry, cleaning products, and even in certain medical contexts where it acts as a disinfectant due to its ability to release oxygen upon decomposition. Therefore the correct option is a.
