test tube A, pour for some water and make sure to seal it with a cork.
Test Tube B, pour boiled water which does not contain dissolved air. Put some oil in the test tube B to form another layer which will prevent air from entering
Test Tube C, put some anhydrous chloride and cork it. Ahnydrous calcium chloride is added to absorb all the moisture present in the air of test tube.
which of the nails in the Test Tube did not RUST?
it has chloride preventing it to rust isn't chloride for cleaning? for stuff? so it's probably with the chloride but after some time it will rust when it gets removed??
