Iron nails are placed in (a) tap water, (b) distilled or filter water and (c) water with a
layer of oil on its surface for a few days. Write your observations in each case.
Answers
Answer:
Rusting (corrosion) is a redox reaction wherein the iron undergoes oxidation while oxygen reduces. Distilled water can readily absorb oxygen from the atmosphere when compared to normal tap water. This helps in rusting.So yes, rusting of iron can take place in distilled water.
Answer:
a) The nail will oxidize(rust). Explanation: This is because of the oxygen dissolved in water.
b)Distilled water can readily absorb oxygen from the atmosphere when compared to normal tap water. This helps in rusting.So yes, rusting of iron can take place in distilled water.
c) When iron nails are placed in water with the layer of oil on its surface then no rust will be formed on the nails as there would only be moisture but not oxygen(oil layer will not allow entry of oxygen)
