Question

When NaCl is dissolved in water, the sodium ion becomes?

Answer 1

Hint: Consider the polar nature of water and then proceed.

 

Complete step-by-step answer:

Inside water, when sodium chloride (NaCl) is dissolved, the sodium ion becomes hydrated.

It dissociates into $N{a}^{+}$ and $C{l}^{-}$ ions because of the polar nature of water $(H_{2}O)$.

$NaCl(s)+H_{2}O\to N{a}^{+}(aq)+C{l}^{-}(aq)$

The $N{a}^{+}$ ions are attracted towards the partially negative oxygen in the water molecule whereas the $C{l}^{-}$ ions are attracted towards the partially positive hydrogen.

 

Note: Such problems can be solved by understanding the nature and behavior of the solute and the solvents.
