How is sodium chloride different from its constituent elements, sodium and chlorine in its properties? Justify

Answer 1

Dear Student, The solution is as follows: 1. Sodium chloride is white crystalline while sodium grey solid metal and chlorine is gas. 2. Sodium and chlorine give exothermic reactions with water while sodium chloride remains unreactive with water. 2 Na (s) + 2 H2O(l) ​→2 NaOH(aq) + H2(g) Cl2(g) + H2O(l) →HOCl(aq) + H+(aq) + Cl-(aq).
