What changes do you observe if you
add a piece of mushroom, squash and banana into a 3% hydrogen
peroxide solution. Why? 
Homework Answers
Most living tissue contains catalase. When we add a piece of mushroom,squash and banana into a 3% hydrogen peroxide solution,we can observe formation of oxygen bubbles.This is due to the reason, Catalase helps change peroxides into water and oxygen.Peroxides aren’t good for living things.

PART A- Observe Normal Catalase Reaction To determine the volume of oxygen released in ml) during the degradation of H202 by catalase, you will first do trials using the set-up in Fig. 1. 1. Place 10 ml of the 3% hydrogen peroxide solution into a clean bottle 2. Add quickly catalase containing solution. 3. What gas is being released? 4. Throughout this investigation you will estimate the rate of the reaction (by measuring the volume of water displaced by O2...

2) During standardization of KMnO4 if you observe a brown precipitate, what does this indicate? Do you continue the titration in this situation or stop and repeat it? 3) Why do we perform blank analysis in KMnO standardization? 4) Why do we add HgCl, and why do we add it quickly? Write the related reaction.

2) Why do you think we add an excess of the relatively unstable hydrogen peroxide or hydrobromic acid to the reaction? Group of answer choices A) Some of the reagent will evaporate due to the heat of reaction B) Some of the reagent will be voted out of the flask. C) Some of the reagent will inherently not be reactive. D) Some of the reagent will be lost to decomposition without having a chance to react.

Part I Color changes of Methyl Violet. We will study the following reaction: HMV (aq) + MV (aq) + H* (aq) yellow greenish-blue violet Step 1. Place about 4 mL of distilled water in a regular test tube. Add two drops of methyl violet indicator. Record the color of the solution. Violet Next, add drop by drop, add 6M HCI. This forces equilibrium to be shifted to the left or right-circle the right answer). Adding HCl changes color from to...
