Acid, Bases & Metals
Play Online Acid, Bases & Metals
When acid touches metal it gives off bubbles. That shows metal breaking down and hydrogen gas forming. Acids, bases and metals shape how we build things and run processes. Understanding their behavior helps keep structures sound and hazards in check.
An acid gives off hydrogen ions when it meets water. It can wear away metals and burn living tissue. You sense a sharp taste in foods that use acid. Hydrochloric acid shows up in lab bottles and industrial vats. A base gives off hydroxide ions in water. It feels slick and leaves a bitter taste. You find these traits in soaps and drain cleaners. Sodium hydroxide and ammonia serve as common examples.
Metals shine and carry heat and electricity. Ferrous metals contain iron. Nonferrous metals do not. You build bridges, cars and wires from these materials. When an acid hits a metal it frees hydrogen gas. That can eat away at pipes and beams. Bases spark that same gas but with less force. Knowing these reactions keeps our tools and buildings safe.
