QUESTION 10 Refer tо Diаgrаm 3 оn yоu аddendum. The diagram shows how hydrogen gas and chlorine gas can be prepared in the laboratory by electrolysis of a concentrated solution of sodium chloride. a The ionic half-equation for the formation of chlorine at the positive electrode is 2Cl− → Cl2 + 2e− a(i) State why this reaction is an oxidation reaction. (1) a(ii) Give the ionic half-equation for the formation of hydrogen at the negative electrode. (1) a(iii) State why it is safer to do this electrolysis in a fume cupboard. (1) a(iv) Suggest why the volume of chlorine collected during this electrolysis is less than the volume of hydrogen collected. (1) c In the chemical industry, chlorine can be produced by the electrolysis of molten sodium chloride. The overall equation for this reaction is 2NaCl(l) → 2Na(l) + Cl2(g) c(i) Explain why sodium chloride needs to be molten rather than solid for electrolysis to occur. (2) c(ii) Calculate the maximum volume, in dm3, of chlorine gas at rtp that can be obtained from 23.985 tonnes of molten sodium chloride. [1 tonne = 106 g] [Mr of NaCl = 58.5] [molar volume of chlorine at rtp = 24 dm3] Give your answer in standard form. volume = ................................dm3 (4) [10]
