Answer:

Nada.........

Explanation:

Litmus paper may change colour depending on the pH of the solution in which it is placed. We has #NaCl(aq)#, which as the salt of a strong acid and strong base does not affect aqueous #pH#,

On the other hand, if we examined the #pH# of say #NaF(aq)#, we would find that the solution was SLIGHTLY basic due to the hydrolytic action of the fluoride ion:

#F^(-)+H_2O(l)rightleftharpoonsHF(aq) + HO^-#
