Decomposition of hydrogen peroxide can be prevented by adding

Step-by-step solution

The decomposition of hydrogen peroxide ( H₂O₂ ) is a catalytic reaction that is often accelerated by impurities, dust, or metal surfaces. To stabilize H₂O₂ and prevent its decomposition, negative catalysts or stabilizers are added to the solution. Acetanilide, phosphoric acid, and urea are commonly used as stabilizers for hydrogen peroxide. These substances act by inhibiting the catalytic activity of trace metal ions that would otherwise promote the decomposition of H₂O₂ into water and oxygen. Among the given optio
