Posted on March 27, 2011 by skiznoki13. Ans: (a) The substance ‘X’ is calcium oxide. Its relative molecular mass is 287 g. Calculate its molecular formula assuming that all the hydrogen in the compound is present in combination with oxygen as water of crystallization. 2 H 2 O(l) → 2 H 2 (g) + O 2 (g); E 0 = +1.229 V. The energy efficiency of water electrolysis varies widely. Page No: 10. The decomposition of pure water into hydrogen and oxygen at standard temperature and pressure  is not favorable in thermodynamic  terms. Lakhmir Singh Chemistry Class 10 Solutions Page No:69. The electrolysis of brine is a large-scale process used to manufacture chlorine from salt. In the cell, two sets of reactions take place at the separate electrodes, oxidations at tâ¦ A small amount of NaOH, anhydrous CuSO 4 and NaCl were added to the beakers A, B and C respectively. The process of electrolysis involves using an electric current to bring about a chemical change and make new chemicals. Tap to unmute. 1. In the electrolysis of water (a) Name the gas collected at the cathode and anode respectively. Pre Boards. The electrolytic cell consists of a pair of platinum electrodes immersed in water to which a small amount of an electrolyte such as H 2 SO 4 has been added. Cut the cardboard piece to a square size thâ¦ (iii) What is common name of compound ‘C’ ? Exothermic Reactions is the flow of the net transfer of heat energy during the reaction is from the medium into its surroundings. Electrolysis is the process by which electric current is passed through a substance to effect a chemical change. Water electrolysis technologies. ... Name the substance 'X' and write its formula. Electrolysis of Water Lab Purpose: To determine the ratio in which elements form water. Up next. Electrolysis of Brine. Brine is a solution of sodium chloride (NaCl) and water (H 2 O). Fill the beaker with warm water. One formula unit of copper sulphate contains five water molecules (5H 2 O). Watch later. Thus, the number of copper (II) ions formed is half the number of electrons. Part of one class period, approximately 10–15 minutes. Concise Chemistry Part II - Selina Solutions for Class 10 Chemistry ICSE, 6 Electrolysis. Logic: According to Faraday's first law of electrolysis: Where: m = mass of substance It then decomposes to ferric oxide (Fe2O3), sulphur dioxide (SO 2) and sulphur trioxide (SO 3).Ferric oxide is a solid, while SO 2 and SO 3 are gases. _____ grams of NaCl + _____ grams of water (One correct ratio is 10 grams of NaCl and 90 grams of water) o Connect the electrodes to the + and -terminals of a 9volt battery. F = 9.65 x 10 4 C mol-1 (or 96500 C mol-1 if you prefer). Carefully remove the metal sleeves and the erasers of the pencils and sharpen both the ends of each. When these bonds split apart, the energy released can be used to do work. During electrolysis, ionic substances are decomposed into simpler substances when an electric current is passed through them.It is equal to 96,500 coulombs.
