Welcome to your Electrolysis 1 Name Email Answer the following questions and fill in the gaps Fill in the gap using the following words (Conduct , decomposed, electrolysis, melted, move , stop and titration) Molten sodium chloride is into sodium and chlorine by Sodium chloride is an ionic compound. Both molten and aqueous sodium chloride will electricity because the ions are free to Match them to their answers Electrolyte Electrolysis Decomposition ionic compound Molten a compound between a metallic element and a non-metallic element. salt has been heated until it melts and forms a liquid To break down a compound into simpler compounds or into elements A process in which electrical energy, from a direct current, decomposes electrolytes An ionic compound which conducts electricity when molten or dissolved in water Answer the following questions A = B = C = D = E = F = Are the ions free to move in solid or molten sodium chloride? solid molten None Does solid sodium chloride or molten sodium chloride conduct electricity? solid molten None Answer the following questions 1) An aqueous solution of potassium chloride is electrolysedWhat forms at the cathode? What forms at the anode? 2) An aqueous solution of sodium bromide is electrolysedWhat forms at the cathode? What forms at the anode? 3) An aqueous solution of copper chloride is electrolysedWhat forms at the cathode? What forms at the anode? 4) An aqueous solution of sodium sulphate is electrolysedWhat forms at the cathode? What forms at the anode? 5)An aqueous solution of zinc iodide is electrolysedWhat forms at the cathode? What forms at the anode? Fill in the gap (use the words to fill the gaps: cathode, anode, electrode, two , atom, four , molecule) Hydrogen (H+) and copper (Cu2+) ions are attracted to the , and hydroxide (OH−) ions and sulfate (SO42−) ions are attracted to the because the ions are attracted to the oppositely charged 1 copper ion accepts electrons to form a copper , Cu 4 hydroxide ions (4 OH−) lose electrons to form an oxygen (O) 1 out of 7 Time's upYou cannot switch tabs while taking this quiz!You are not allowed to switch tabs violation has been recorded.you cannot minimize full screen mode!You are not allowed to minimize full screen while taking this quiz, violation has been recorded.Access denied!
