What are liquids that when mixed, even in small amounts, explode?

There are several combinations of liquids that, when mixed, can produce explosive reactions. It's essential to understand that Safety is the priority! Here are two known combinations: 1. **Acids and Bases**: Mixing strong acids (like sulfuric acid) with strong bases (like sodium hydroxide) can create exothermic reactions that may lead to boiling, splattering, or, in some cases, explosive reactions. 2. **Hydrogen Peroxide and Acids**: When concentrated hydrogen peroxide is mixed with certain acids (like sulfuric acid), it can lead to the production of oxygen gas rapidly, and in some circumstances, it can result in violent reactions. 3. **Acetone and Nitric Acid**: Combining acetone with nitric acid can create an explosive compound called "acetone peroxide." 4. **Certain Metal Hydrides**: Mixing water with metal hydrides (like lithium hydride) can produce hydrogen gas rapidly, which can be explosive if ignited. These combinations can be extremely dangerous and are often used in controlled environments by professionals. It is critical never to attempt mixing chemicals without proper knowledge, safety equipment, and training.
