The Student Then Sets Up Two More Test Tubes Containing Iron NailsExplain Why class=

Sagot :

test tube 1 does not rust because boiled water has no oxygen and oil stops new oxygen from entering and without oxygen iron cannot rust.

test tube 2 does not rust because the drying agent absorbs all the moisture from air, and moisture is required for iron to rust.

In the absence of oxygen or moisture rusting of the nail can not take place.

There are two very important things that must be present for the process of rusting to take place these are;

  • Oxygen
  • Moisture

If we can exclude these two, rusting will not take place in the absence of either of them.

Rusting does not occur in tube 1 because the water have been boiled and the oxygen removed then it is stored under oil that prevents corrosion.

In tube 2, there is a drying agent that removes moisture from air hence moisture does not have access to the nail so it does not rust.
