Question 5:<\/strong> Choose A, B, C or D to match the descriptions (i) to (v) below. Some alphabets may be repeated.
\nA. non-electrolyte
\nB. strong electrolyte
\nC. Weak electrolyte
\nD. metallic conductor
\n(i) Molten ionic compound
\n(ii) Carbon tetrachloride
\n(iii) An aluminium wire
\n(iv) A solution containing solvent molcules, solute molecules and ions formed by the dissociation of solute molecules.
\n(v) A sugar solution with sugar molecules and water molecules.

Question 6:<\/strong> Give three differences between sodium atom and sodium ion.
\nAnswer:<\/strong> (i) Sodium atom is neutral in nature, while sodium ion is a positively charged particle.
\n(ii) Sodium atom vigorously reacts with water to liberate hydrogen gas, while sodium ion does not react with water.
\n(iii) Sodium atom tends to lose an electron to form sodium ion with a complete octet in the outermost shell.<\/p>\n

Question 7:<\/strong> Explain how electrolysis is an example of a redox reaction.
\nAnswer:<\/strong> Redox reactions are called simultaneous oxidation-reduction reactions. In electrode reactions, the positively charged ions (cations) accept electrons from the cathode to form neutral atoms, i.e., at cathode reduction takes place. At the anode, the negatively charged ions (anions) lose electrons to form neutral atoms, i.e., anode oxidation takes place. So, electrode reactions also signify oxidation-reduction reactions. Hence, they are also called Redox reactions.<\/p>\n
