Los ácidos y los álcalis (segunda parte)

The video explains neutralization reactions, where acids and bases react to form a neutral solution. It highlights everyday examples like antacids neutralizing stomach acid and industrial applications such as producing chemicals. The video also discusses how divers use neutralization to recycle air, allowing them to stay underwater longer. Overall, neutralization reactions are crucial in both creating useful products and removing harmful substances.
