Question

 Give reasons why copper is used to make hot water tanks and not steel (an alloy of iron).

Solution

Copper does not react with cold water, hot water, or steam. However, iron reacts with steam. If the hot water tanks are made of steel (an alloy of iron), then iron would react vigorously with the steam formed from hot water.3Fe + 4H2O → Fe3O4 + H2O
That is why copper is used to make hot water tanks, and not steel.

  Is there an error in this question or solution?
