iron in salt water is supposed to rust faster than in distilled water. but the distilled rusted it faster.?

Question

any ideas/help?

Answer 1

Distilled water is extremely corrosive. People make the mistake of feeding distilled water into higher purity stills. It will actually disolve stainless steel and when boiling, actually disolve significant parts of borosilicate (Pyrex) glasses. DI water can be fed into stillls because they usually still have enough minerals to prevent the stills from disolving. The old tin block stills were and still are very good.

Answer 2

Iron rusts no longer through the undeniable fact that is geared up in contact with water, yet because electron move has occured and iron then reacts with some type of oxidizer (oxygen can artwork for this). Water enables facilitate this procedure through giving a medium for the reaction to ensue. for this reason distilled water can nevertheless rust iron. With salt further, ions are waiting to flow more advantageous positive. that is also why distilled water gained't carry electricity yet salt water will.

Answer 3

The distilled water probably had more dissolved oxygen - essential for rusting.

Answer 4

Distilled water does not have any dissolved chemicals, which may actually retard rusting process. Hence the difference
