can anyone give some comments or inferential analysis to the research presented below? thank you :D some info and answers to the topic questions would be nice to hear too! "To compare the action of catalase and manganese dioxide on hydrogen peroxide." 1. Label 4 test-tubes A, B, C and D. 2. To each tube add 5cm3 of hydrogen peroxide. 3. Prepare the contents of the 4 tubes as shown in the table below. For each tube record the observations. Test any gas given off with a glowing splinter. TEST TUBE AND CONTENTS: A. 5cm3 hydrogen peroxide solution + 1 small pieace of fresh liver B. 5cm3 hydrogen peroxide solution + 1 small piece of boiled liver (Boil the liver for 10 minutes and cool before use.) C. 5cm3 hydrogen peroxide + a little manganese (IV) oxide D. 5cm3 hydrogen peroxide solution + a little boiled manganese dioxode (The manganese dioxide has been boiled and cooled before use.) 4. What type of substance is in the liver which could bring about the reaction in tube A? 5. How do you account for your observation in tube B? 6. From your observation on D, what can you conclude about manganese (IV) oxide? 7.Repeat experiments A and B using a piece of potato tuber.
