Question

what happens when :
(1) sodium chloride is added to water with constant stirring.
(2) it is easier to remove fresh stains of ink from a cloth then stains caused a few days ago.

Answer 1

it will become sodium chloride solution

Answer 2

1. the stirring causes more collisions on a molecular level. this allows for an increased rate of particle dissociation,which in turn disolves the sodium chloride faster.
2.when it is few days ago then it is harder to remove because it was absorbed by the cloth
