Compare the equipment used for the lab process of making ammonia as compared to the industrial process of making ammonia
• LAB: simple equipment, prepared using a titration apparatus • INDUSTRIAL: hugely expensive and complex
Compare the reactant concentration for the lab process of making ammonia as compared to the industrial process of making ammonia
• LAB: low concentrations, less heat given off • INDUSTRIAL: high concentrations, extremely exothermic reaction
Compare the methods of separation used for the lab process of making ammonia as compared to the industrial process of making ammonia
• LAB: crystallisation, slow process • INDUSTRIAL: heat produced to evaporate water from the reaction mixture to make very concentrated ammonia nitrate product
What happens at the anode during a reduction?
• oxidation • anions lose electrons
What happens at a cathode during electrolysis?
• reduction • cations gain electrons
