NaOH is expected to have a higher reactivity compared to NaCl, based on their electronic configuration.NaCl is an ionic compound formed by the transfer of an electron from sodium Na to chlorine Cl , resulting in the formation of a stable, electrostatic attraction between the positively charged sodium ion Na+ and the negatively charged chloride ion Cl- . The electronic configuration of Na+ is [Ne] and Cl- is [Ar], both of which have a stable, full outer electron shell.NaOH, on the other hand, is also an ionic compound formed by the transfer of an electron from sodium Na to the hydroxide ion OH- . The electronic configuration of Na+ is [Ne] and OH- is [He] 2s 2p 3s 3p 3d 4s. The presence of the hydroxide ion OH- makes NaOH a strong base, which is highly reactive with acids, and can undergo various chemical reactions such as neutralization, hydrolysis, and redox reactions.In summary, NaOH is expected to have a higher reactivity than NaCl due to the presence of the hydroxide ion OH- and its ability to participate in various chemical reactions.
