Explain why hydrogen peroxide would be more effective as a disinfectant on inanimate surfaces as opposed to living tissue?
Homework Answers
Hydrogen peroxide serves as a good disinfectant as it produces peroxide free radicals which can interact with inanimate chemical compounds to produce different compounds.
Living organisms are also affected by hydrogen peroxide as it can denature macromolecules present on their surface.
But, living organisms are equipped with special organelles known as peroxisomes which can neutralize hydrogen peroxide.
Hence, living organisms can exhibit moderate tolerance to hydrogen peroxide.

Enter your answer in the provided box. Dilute aqueous hydrogen peroxide is used as a bleaching agent and for disinfecting surfaces and small cuts. Its concentration is sometimes given as a certain number of "volumes hydrogen peroxide," which refers to the number of volumes of Oz gas, measured at STP, that a given volume of hydrogen peroxide solution will release when it decomposes to...

Q1: Define the difference between an antiseptic and a disinfectant. Q2: Why is the disk diffusion method a viable method for determining the effectiveness of a disinfectant? Q3: Gram negative and gram positive organisms tend to have different sensitivities to the same disinfectant. What would explain this? Q4: 100% ethanol is less effective than 70% alcohol. Why?

K= 1.54day-1
Hydrogen peroxide is used to disinfect porous surfaces like N95 masks by heating the liquid to 100C to make a vapor. Hydrogen peroxide liquid is stored as a 3.0% w/w solution at room temperature, but it quickly decomposes into water and oxygen in a first-order process. H2O2(aq) + H2O(l) + 1/2 O2(g) 4) If the initial concentration of Hydrogen peroxide is 0.52 M, what is the H2O2 concentration after 7.00 days? Use the equation In (X/Xf=kt a) 0.000012...
