Reacting alkali metals with acids can be dangerous because it produces highly exothermic reactions that release large amounts of heat, along with flammable hydrogen gas. This can lead to potential explosions or the release of toxic fumes. Additionally, the reaction can be difficult to control and can result in the splashing of corrosive liquids.
