WebThe aim of this investigation is to find out how Copper Sulphate in a reaction affects the way catalase works, in the same reaction (). ... These R groups ensure that the enzyme stays soluble. () An enzyme is a very large molecule but only a small part of it is involved in the reaction. This small part is called the active site. WebIn this experiment, students react an insoluble metal oxide with a dilute acid to form a soluble salt. By reacting copper(II) oxide, a black solid, with colourless dilute sulfuric acid, they produce copper(II) sulfate with a characteristic blue colour. Students can then obtain blue copper(II) sulfate pentahydrate crystals
