How We Learned That Water Isn't An Element

The video explores the historical journey of understanding water's composition. Initially thought to be an element, water was later discovered to be a compound made of hydrogen and oxygen. Through experiments in the 1780s, chemists demonstrated that water could be created from simpler substances, debunking the idea of it being an element. The process of electrolysis further revealed water's building blocks. John Dalton's early model of water was incorrect, but Avogadro's breakthrough on gas volumes led to the correct understanding of water as H2O. This discovery was a significant achievement in chemistry.
