To prevent violent reactions when handling acids, what is the best practice?

Wear rubber gloves

Never pour water into an acid

To prevent violent reactions when handling acids, the best practice is to never pour water into an acid. This principle is crucial because when water is added to a concentrated acid, it can lead to a violent exothermic reaction. The heat generated from this reaction can cause the acid to splatter or even boil, which poses a significant risk of burns or damage.

In contrast, adding acid to water is a safer approach. This method allows for better control of the reaction and helps to dissipate the heat more effectively. Water's larger volume can absorb the heat, reducing the risk of splattering. The other options, while they represent important safety measures or practices, do not specifically address the immediate and critical risk associated with the order of mixing acid and water.
