WebAnswer:A is sodium (burns with golden flame), B is chlorine (atomic number 17), C is sodium chloride and D is sodium hydroxide. When sodium reacts with chlorine, it gives sodium chloride. Na + Cl ⇨ NaCl Electrolysis of sodium chloride gives sodium hydroxide. 2NaCl + 2H2O ⇨ 2NaOH + Cl2+ H2 Question 66: Two ores A and B were taken. WebA is sodium (Na) because it burns with golden flame in air. B is chlorine () as its atomic number is 17. When Na reacts with,is formed. Hence, C is sodium chloride (). Aqueous solution of, on electrolysis gives sodium hydroxide. Thus, D is sodium hydroxide (). warning Report Error Previous Next
