Copper's Reactivity with Water

The video explores what happens when solid copper is placed in water. It discusses two methods to determine the reaction: testing it directly or using the activity series. The activity series ranks elements by reactivity, with copper being less reactive than hydrogen. As a result, copper cannot displace hydrogen in water, leading to no reaction. This is consistent with everyday observations, such as a wet penny remaining unchanged. The video concludes that copper, along with metals like silver, gold, and platinum, does not react with water.
