Describe the structure of hydrogen peroxide
WebHydrogen peroxide decomposes slowly in light to produce oxygen and water. The enzyme catalase can speed up (catalyse) this reaction. In this practical, students investigate the presence of enzymes in liver, potato and celery by detecting the oxygen gas produced when hydrogen peroxide decomposes. The experiment should take no more than 20–30 ... WebHydrogen peroxide, which was discovered as a chemical compound in 1818, is the most basic member of the peroxide class. The primary manufacturing procedures include …
