7 Exploring Group IV Elements' Reactions with Water, Acids, and Bases

The video tutorial explores the chemical reactivity of Group 4 elements, focusing on their interactions with water, acids, and sodium hydroxide. It highlights that reactivity increases down the group, with tin reacting with water to form tin oxide and lead forming a protective oxide layer. In reactions with acids, carbon, silicon, and germanium show no reaction with dilute nitric acid, while tin and lead form nitrates. With sodium hydroxide, carbon shows no reaction, but silicon, tin, and lead form metal oxides and release hydrogen gas.
