45 electrolysis of water lab answers
Electrolysis of Water Lab Flashcards | Quizlet Electrolyte a solution that conducts electricity solution liquid mixture of 2 or more substances mixed together Electrodes metal rods immersed in the solution Cathode negative electrode (black wire) Anode positive electrode (red wire) Battery power source contains energy stored in the form of chemical energy Ratio of hydrogen gas to oxygen gas 2:1 Electrolysis of Water Experiment - Splitting Water | HST Electrolysis is the process by which an electric current is passed through a substance to affect a chemical change. The chemical change occurs when the substance loses electrons (oxidation) or gains them (reduction). In the two experiments listed below, the first reactive substance is water and the second one is a copper sulfate solution.
Electrolysis: Splitting Water - Stanford University Electrolysis: Splitting Water Teacher Version In this lab you will use a battery to perform electrolysis, or chemical decomposition, of different aqueous solutions (like water) to produce gases (like hydrogen and oxygen in the case of water). You will measure the volumes of gas produced and compare this to the predicted ratios from chemical ...
